Traffic and Transport Construction Impacts of New M5 – Summary of AECOM’s EIS

Ploughing through the whole EIS can be time consuming and tedious as there is so much repetition in the Westconnex EIS documents.

Researcher Anthony McCosker has provided us with a summary of the construction impacts as set out in New M5 EIS Appendix G on Traffic and Transport which consists of 298 pages.

This post should  be read in conjunction with Anthony McClosker’s comment on this section.

Later, we will provide a summary of the information in the EIS relating to the operation of the WestConnex project (note that some information deemed relevant to both summaries will cross over and be repeated or revisited).

An overview of traffic and transport impacts resulting specifically from construction works is given as:

Surface work required to:

  • Support tunnelling activities
  • Construct the tunnel portals
  • Construct the western surface works
  • Construct the St Peters interchange
  • Undertake local road upgrades
  • Construct the motorway control centre
  • Construct the ventilation facilities
  • Construct tunnel support facilities
  • Construct ancillary operations buildings and facilities

Construction hours

  • Tunnelling, tunnelling support and underground construction activities including tunnel excavation, spoil handling and haulage and underground construction and fit-out—24 hours a day/7 days a week
  • Out of hours activities for safety/operational reasons—at any time
  • Surface construction activities—7am-6pm weekdays; 8am-1pm Saturdays
  • Blasting and rock breaking—8-6 weekdays, 8-1 Saturdays
  • Minor or ancillary activities—any time

Given that much of the work on this stage of the WestConnex project will be performed underground, it would be assumed that the major traffic impacts will occur around the at-surface compounds and worksites. The following compounds are identified in the report (Appendix G, pp. 83-95) as:

  • Kingsgrove North
  • Kingsgrove South
  • Commercial Road
  • Bexley Road North
  • Bexley Road South
  • Bexley Road East
  • Arncliffe
  • Canal Road
  • Campbell Road
  • [Alexandria] Landfill Closure construction compound
  • Burrows Road
  • Cambpell Road Bridge
  • Gardeners Road Bridge
  • Sydney Park

Community facilities close to the construction works are listed in Chapter 15 (Social and Economic) but the traffic section does acknowledge that “During the construction of the project, there is the potential for positive and negative impacts on residents, businesses, road users (including commercial and freight vehicles), users of community facilities and the wider community” (Appendix G, p. 100)

Ed: The People’s EIS has noticed that this section of the EIS has gaps and errors. 

Traffic and other impacts of construction compounds

Proposed periods of construction in different locations are noted in the Appendix G. Construction will occur mostly over 2 – 3 year periods between 2016 and 2019.

Western and Bexley Road surface works construction compounds:

Kingsgrove North construction compound (2016-2019) (Appendix G, pp. 101-102):

  • Located to the north of existing M5 East Motorway, within Beverly Grove Park
  • Realignment of shared path through Beverly Grove Park, demolition of existing structures (buildings, noise barriers etc), establishment of site offices and temporary infrastructure, stockpiling of fill and paving materials, construction of “cut and cover” structure at tunnel entry, construction and sinking of a shaft for tunnelling works, excavation of eastbound main alignment tunnel (including stockpiling materials, drilling, controlled blasting), tunnel completion works and installations, delivery and storage of materials
  • Heavy and light vehicle access via Garema Circuit, Kingsgrove and by the M5 East Motorway, and also Wirega Avenue and Moorefields Road
  • Almost 1,000 light vehicle and 2,000 heavy vehicle daily movements
  • 170 employee parking spaces provided on-site, likely employee peak 200
  • Temporary noise barrier necessary

Kingsgrove South construction compound (2016-2019) (Appendix G, p. 103):

  • To the south of the M5 East Motorway, within Beverly Grove Park
  • Demolition of existing structures (buildings, noise barriers etc), stockpiling of materials, construction of Kingsgrove South motorway operations complex and rehabilitation and landscaping
  • Pedestrian and cyclist access “generally maintained” via the Kindilan underpass (closed for four weeks), also Garema Circuit, M5 East, Wirega Avenue and Moorefields Road
  • Heavy and light vehicle access via Kindilan Underpass from Kingsgrove North construction compound, 20 employee parking spaces provided on-site

Commercial Road construction compound (2017-2019) (Appendix G, p. 109):

  • Southern side of M5 east Motorway on a private property

  • Heavy and light vehicle access via Commercial Road—local road
  • 133 light vehicle and almost 200 heavy vehicle daily movements

Bexley Road North construction compound (2016-2019) (Appendix G, p. 110):

  • Western side of Bexley Road and north of the M5 East Motorway near the intersection of Bexley Road and Poole Street on vacant land
  • Site establishment, acoustic shed and noise barriers, shaft for tunnel works, tunnel excavation and storage, drilling and controlled blasting, installation of completed tunnel infrastructure
  • Entry to site from Bexley Road—also using King Georges Road, M5 East, Canterbury Road, Forest Road and Stoney Creek Road
  • Almost 100 light vehicle and 450 heavy vehicle daily movements

Bexley Road South construction compound (2016-2019) (Appendix G, pp. 115-116):

Level of Service (LoS)* of intersections (Appendix G, pp. 131-132)

  • Near the Western and Bexley Road surface areas LoS is predicted to remain similar
  • It will worsen for Kingsgrove Road/Homer Street (LoS D to E), Kingsgrove Road/Moorefields Road (B to C) and Kingsgrove Road/Commercial Road/Kingsgrove Avenue (B to C)
  • Congestion also predicted along Homer Street at Bexley Road and Kinsgrove Road intersections—a street which is already operating at LoS F and so is projected to worsen
  • Also, Moorefields Road/Wirega Avenue/Chapel Street intersection close to capacity and will deteriorate to LoS E with construction traffic in morning peak due to construction traffic

Level of Service of mid-block (Appendix G, pp. 132-133):

Traffic levels are assumed in the report to remain similar to existing non-construction levels, with most roads (not listed in the report) to have LoS D or better functioning, except for:

  • M5 East Motorway east of King Georges Road (LoS D to E)
  • Eastbound on M5 East, east of Bexley Road in the tunnel (E to F)
  • Sections of King Georges Road and Moorefields Road remaining at LoS E
  • Also, not noted in the text but noted in the table (Appendix G, pp. 135-136) is the fact that road conditions worsen in seven blocks due to projected construction traffic, not just those two mentioned in the report’s text

There will be a speed limit reduction to 80km/hour roadwork speed—estimated at a one minute delay on travel times, and where necessary local streets reduced from 50km/hour to 40km/hour

As outlined above, construction compounds require access from local roads, so “motorists may experience small increases in delays due to the increase in traffic volumes when exiting from the existing properties and on-street parking along the local roads affected by the construction vehicle routes” (Appendix G, p. 146)

Construction traffic from the Western and Bexley Road surface works construction compounds alone will consist of 4,860 vehicles a day (Appendix G, p. 146), 64% of these heavy vehicles and summing to almost 4% of existing traffic on the M5 East Motorway:

“An increase in traffic flow, particularly heavy vehicles, on the existing road network during the construction period would result in increased delays at intersections along the identified construction vehicle routes. Buses would also be subjected to the same delays as general traffic due to reduced speed limits or during manual traffic control” (Appendix G, p. 146)

 

  • The following public transport routes servicing the area would experience delay, along with general traffic flow in the same areas: Routes 400, 446, 450, 490, 491, 493, 495, M41, R46, school buses, longer travel times and reduced pedestrian amenity to reach public transport services and temporary closure/relocation of bus stops (Appendix G, pp. 146-148)
  • Cyclist and pedestrian facilities affected in the area include: realignment of shared path in Beverly Grove Park to the north of the M5 East; closure during construction of shared path in Beverly Grove Park to south of M5 East; closure of Kindilan underpass for four weeks along with further intermittent closures, removal of cyclist access to M5 East (King Georges Road to Bexley Road)
  • Pedestrians will experience reduced amenity in the area due to local construction traffic while cyclists will experience increased on-road wait times similar to local traffic, increased journey time and distance given closures to shoulders and detours, and reduced overall amenity and safety of the area

Arncliffe surface works:

Arncliffe construction compound (2016-2019) (Appendix G, p. 149-150):

  • Within Kograrah Golf Course
  • Earthworks, site office construction, ventilation facility construction, stockpiling material, tunnel excavation, permanent ventilation access construction, tunnel completion works, construction of Arncliffe motorway operations complex including ventilation facility and water treatment plant, landscaping
  • Vehicle access from Marsh/Flora Street, a total of 374 daily light vehicles and 1,055 daily heavy vehicles planned to access the compound
  • 220 employee parking spaces on-site, likely employee peak 300
  • March/Flora Street projected to worsen from LoS A to B due to construction traffic
  • Other intersections projected to remain at similar LoS, though it is also noted that Princes Highway/Wickham Street is already at LoS F and so the effect of additional construction traffic “the performance of the intersection is forecast to decrease further. As the intersection is operating beyond its capacity, it is susceptible to large increases in delay with only small levels of increased demand” (Appendix G, p. 154)
  • Modification to traffic signalling and layout at Marsh/Flora Street intersection also necessary
  • Mid-block LoS projected to remain similar to ‘without project’ levels, however part of Wickham Street will decline in LoS (D to E) and parts of West Botany and Marsh Streets are predicted to operate at or beyond capacity without the project, so additional construction traffic will significantly affect these roads
  • Marsh Street will be temporarily closed at night periods for changed traffic signal installations
  • Temporary 40km/hour speed limit might be introduced for some roads
  • Bus routes impacted by increased construction traffic volumes include Routes 400, 410 and 422, as well as school bus routes and longer walk times to bus stops, reduced amenity and safety for people walking to bus stops, and temporary closure or relocation of bus stops
  • For pedestrians, increased heavy vehicles will reduce overall amenity in the area, and for cyclists it will increase delays, increase journey times given closed shoulders and detours, an reduce overall amenity

St Peters interchange construction compounds:

Canal Road construction compound (2016-2019) (Appendix G, pp.162-164):

  • Located at former Alexandria Landfill site (St Peters)
  • Site establishment, demolition of buildings, “cut and cover” structure constructed, piles installed for on/off ramps, excavation of tunnels, excavation of ventilation tunnels, stockpiling of materials and spoil haulage (24 hours/day, 7 days a week), drilling and blasting, construction of St Peters motorway operations complex, dive excavation for tunnelling, tunnelling support (such as spoil removal), project installation and finishing
  • Temporary noise barrier 2.5m necessary
  • Bus sop to eastern side of Canal Road relocated
  • 1,132 daily light vehicles and 710 daily heavy vehicles
  • 290 employee parking spaces on-site, likely employee peak 320:

Campbell Road construction compound (2017-2019) (Appendix G, p. 164-165):

  • South side of Campbell Road, between Woodley and Harber Streets, St Peters
  • Site establishment, demolition of existing buildings, construction of on/off ramps at St Peters, construction of carriageways, finish works
  • Access via Campbell Road
  • Over 1,000 light vehicles and over 700 heavy vehicles daily
  • 3m hoarding necessary

Landfill Closure construction compound (2016-2019) (Appendix G, p. 165):

  • Southern side of Campbell Road, at Alexandria Landfill, access via Campbell Road
  • Site establishment, access roads installed, demolition of buildings and other infrastructure, relocation of utilities, landfill closure works (such as earthworks, foundation treatments and capping), landscaping
  • 170 light vehicles and over 200 heavy vehicles daily

Burrows Road construction compound (2016-2019) (Appendix G, p. 166):

  • South-western corner of Campbell Road and Burrows Road, access via Burrows Road
  • Site establishment works, demolition of buildings, construction of hardstand, storage of materials, construction of motorway control centre
  • 260 light vehicles and 200 heavy vehicles daily

Campbell Road Bridge construction compound (2017-2019) (Appendix G, p. 166-168):

  • South-eastern side of Burrows Road, opposite Campbell Road, access via Burrows Road
  • Site established for construction activities, demolition of buildings, stockpiling materials, utilities relocation, support for new bridge construction, storage area for plant and equipment, finishing works
  • Almost 80 light vehicles and 120 heavy vehicles daily, 10 employee parking spaces on-site and likely employee peak of 15

Gardeners Road bridge construction compound (2017-2019) (Appendix G, p. 168-170):

  • South of Burrows Road on WestConnex Development Authority-owned land, access via Burrows Road
  • Site establishment, demolition of buildings, relocation of utilities, storage of construction plant and equipment, stockpiling construction and bridge materials, pre-assembly of segments and finishing works
  • 260 light vehicles and almost 200 heavy vehicles daily, 10 employee parking spaces on-site

Sydney Park construction compound (2018-2019) (Appendix G, p. 170):

  • Northern side of Campbell Road, St Peters, access via Campbell Road
  • Site establishment, construction activities, plant and equipment storage area
  • Almost 100 light vehicles and over 60 heavy vehicles daily

Overall, the St Peters construction precinct will lead to 3,035 additional construction light vehicle movements and 2,218 heavy vehicle movements daily

Intersections in the St Peters construction precinct projected to be affected by construction traffic include:

  • Princes Highway/Railway Road
  • Princes Highway/Canal Road
  • Canal Road/Burrows Road (LoS C to D)
  • Princes Highway/Campbell Road
  • Campbell Road/Euston Road
  • Campbell Road/Burrows Road

Further congestion projected for:

  • Princes Highway/Railway Road
  • Princes Highway/Canal Road
  • Canal Road/Burrows Road

These roads will be operating at LoS F and, “As the intersections are operating beyond their capacity, they are susceptible to large increases in average delay with only small levels of increased demand” (Appendix G, p. 181)]

“It is noted that although the additional traffic from the construction compounds would cause delays when added to the background traffic flow on the roads, further delays to motorists are anticipated due to the construction activities in the area, such as the local road upgrades and intermittent installation of new barriers and realignment of the road to allow for temporary and/or permanent traffic switches” (Appendix G, p. 181)

The following roads are to be heavily used by construction traffic and are analysed in the report in terms of their mid-block performance:

  • Princes Highway
  • Canal Road
  • Burrows Road
  • Campbell Road

Princes Highway and Campbell Road will be operating above capacity regardless of construction traffic, so the effects of even a minor increase will be compounded

Canal Road will change from LoS D to LoS E due to construction traffic, and 5 roads in the St Peters precinct are projected to decrease in overall LoS

Temporary/permanent road closures:

  • Campbell Lane, Woodley Street, Harber Street, Holland Street: All properties along these roads compulsorily acquired and the roads permanently closed
  • Brown Street: Potentially long-term, traffic control and detours
  • Florence Street: Short term, traffic control and detours
  • Bedwin Road, Unwins Bridge Road, Campbell Street, Campbell Road, St Peters Street, Church Street, Princes Highway, Euston Road, Burrows Road, Sydney Park Road, Huntley Street, Bourke Road, Gardeners Road: Intermittent barriers and realignment of the road to allow for temporary and/or permanent traffic switches

Temporary lane closures:

  • Canal Road: Installation of traffic signals
  • Bedwin Road, Unwins Bridge Road, Campbell Street, Campbell Road, Brown Street, Florence Street, St Peters Street, Church Street: Traffic barriers and realignment of the road to allow for temporary and/or permanent traffic switches
  • Princes Highway, Euston Road, Burrows Road, Sydney Park Road, Huntley Street, Bourke Street, Bourke Road, Gardeners Road: Intermittent installation
  • Some areas required to have a speed limit reduction

 

“as the construction compounds are surrounded with local roads, use of the local roads is unavoidable to support the construction activities”: Canal Road, Campbell Road, Burrows Road (Appendix G, p. 185-186)

 

“Due to the extensive change in the road layouts for the construction and operation of the St Peters interchange and the local road upgrade works, a number of properties along Campbell Road, Canal Road and Burrows Road would be acquired and some properties along Euston Road and Gardeners Road would have temporary modifications to driveways as part of construction works and road widening” (Appendix G, p. 186).

Temporary impact on car parking in St Peters and Mascot due to construction includes:

  • Albert Street—loss of 44 on-street car parks
  • Campbell Road (between Campbell and Sydney Park Roads)—loss of 111 car parks
  • Euston Road (between Campbell and Sydney Park Roads)—loss of 112 car parks
  • Burrows Road (south-west of Campbell Road)—loss of 38 car parks
  • Burrows Road (north-east of Campbell Road)—loss of 23 car parks
  • Euston Road (north of Sydney Park Road)—loss of 24 car parks
  • Huntley Street (east of Euston Road)—loss of 32 scar parks
  • Barwon Park Road (north of Campbell Road)—loss of 6 car parks
  • Princess Highway—loss of 30 car parks
  • May Street—loss of 50 car parks
  • Unwins Bridge Road—loss of 39 car parks
  • Brown Street—loss of up to 16 car parks
  • Florence Street—loss of up to 16 car parks
  • St Peters Street—loss of up to 12 car parks
  • Hutchison Street—loss of up to 10 car parks
  • Gardeners Road (west of Bourke Street)—loss of 10 car parks
  • Gardeners Road (between Kent Road and Gardeners Road)—loss of 47 on-street car parks and 20 off-street parks
  • Bunnings Mascot—loss of 25 off-street car parks
  • Bourke Road (north of Bourke Street/Gardeners Road intersection)—loss of 26 off-street car parks

The total figure is not given in the report, but it totals to 691 lost car parking spaces due to construction, in the St Peters and Mascot areas alone

Construction traffic will account for just under 9% of total traffic along Canal Road, with about 40% of this figure heavy vehicles, while “the construction traffic of 1,500 vehicles per day anticipated along Campbell Road would be approximately fourteen per cent of the total existing traffic on Campbell Road in the study area (around 11,300 vehicles per day). The number of crashes for Campbell Road may increase and any foreseen impacts to road safety for all users during construction should be mitigated through the provision of tailored traffic management plans and measures” (Appendix G, p. 186)

The bus routes operating in St Peters will be subject to the same delays as general traffic. These routes include Routes 348, 418 and 422, as well as school bus services and also relocation of bus stops, either temporarily (such as at Euston Road northbound, south of the intersection with Maddox Street) or permanently (such as that at Canal Road, southbound near the Princes Highway)

The following stops will be removed at the start of construction, and reinstated at a time not specified in the report:

  • Princes Highway (southbound) outside 136 Princes Highway, St Peters
  • Bourke Road (northbound) outside 81A to 83 Bourke Road, Mascot
  • Bourke Road (southbound) outside 520-530 Gardeners Road, Mascot
  • Gardeners Road (eastbound) outside 538 to 540 Gardeners Road, Mascot (Appendix G, p. 187)

Longer travel times to and from bus stops, as well as reduced amenity for bus users waiting at stops and reduced roadside safety due to increased numbers of heavy vehicles are also expected as a result of the construction

Pedestrian and cyclist facilities to be temporarily or permanently diverted/realigned due to the St Peters interchange and local road upgrades include (Appendix G, p. 192):

  • Bourke Street bicycle path temporarily diverted
  • Pedestrian and shared paths subject to relocation or to be provided with temporary access paths during construction
  • “Concrete barriers would be installed to separate construction equipment from members of the public where a haul road is close to a pedestrian access”
  • “Along Campbell Road / Campbell Street, Euston Road, Bourke Road, Bourke Street, Gardeners Road and Princes Highway (where it intersects with Campbell Street), the footpath would be affected due to the varied and periodic footpath closures and deviations for road widening. Pedestrians would be diverted to an alternative route or alignment”
  • A strategy to deal with these issues has not yet been created—to be completed as part of Construction Traffic Management Plan

Increased heavy vehicle volumes will impact on walking and cycling amenity, including (Appendix G, p. 192):

  • Reduced overall amenity throughout the project area for those walking and cycling
  • Increased intersection delays for cyclists due to increased traffic
  • Increased journey times and distance due to closed shoulders and detours

Residents and businesses could be negatively impacted by construction workers parking on local streets, with decreased parking available for business customers…Construction personnel would be encouraged to use public transport, active transport or other options, such as car-pooling” (Appendix G, p. 192)

In terms of the entire New M5 project, 3.2 million cubic metres of surplus spoil is projected to be generated, which then requires offsite reuse or disposal (see Table, below). No decision has been made as to where to dump the spoil as yet, however potential sites given include:

  • 330 Captain Cook Drive, Kurnell (15km from project site)
  • 738-780 Wallgrove Road, Horsley Park (40km away)
  • 75 Townson Road, Schofields (55km away)
  • On land west of Riverstone (60km away), and/or
  • 49 Manorhouse Boulevard, Quakers Hill (60km away) (Appendix G, p. 194)

While potential routes are hinted at in Figures 59-61 which outline routes for B-double trucks, minimum clearances of 4.6m and higher mass limit routes (Appendix G, pp. 195-199), the exact routes cannot be known until a spoil site is chosen, however spoilage routes from each construction compound to state or regional roads are given above (in construction compound traffic summaries).

 

TABLE 67 P 201

Table 67. Spoil and non-spoil related heavy vehicles for each construction compounds (Appendix G, p. 201)

Cumulative construction impacts considered against other WestConnex work, and also other nearby developments:

WestConnex works:

King Georges Road Interchange Upgrade:

  • Widening and upgrading existing M5 between Penshurst and Kooemba Road, Beverly Hills, and upgrades to ramps
  • East of King Georges Road the eastbound on-ramp would be extended east and a new bridge constructed north of the Cooloongatta Road overbridge, also westbound off-ramp extended eastward and new bridge span constructed south of Coollongatta Road overbridge
  • Cumulative impacts expected as works cross-over, but details or severity not provided in report

WestConnex Stage 1:

  • Simultaneous construction, however it is stated that “it is unlikely there would be an overlap of construction heavy vehicle routes between the two projects…[and] there is unlikely to be a significant cumulative impact in the vicinity of the project” (Appendix G, p. 203)

Other major developments nearby:

  • Marrickville Metro Shopping Centre extension:
    • Construction traffic may contribute to overall impacts, especially at St Peters (no further details given)
  • Green Square development
  • Mascot Station Town Centre Precinct Masterplan
  • Wolli Creek redevelopment area

Environmental management measures regarding traffic and transport to be taken include (Appendix G, pp. 207-208):

  • Traffic Management and Safety Plan creation (pre-construction)
  • Road dilapidation reports prepared (pre-construction)
  • Construction staging and temporary works developed
  • Vehicle routes to maximise use of arterial roads
  • Oversized vehicles to gain permits from RMS
  • Land occupancies planned to provide safe work area
  • “Measures would be implemented to safely manage pedestrians to and from bus stops, car parks, shopping centres, businesses, homes and any directly affected schools during construction. This includes selecting site compound access and egress points which avoid school children pedestrian access routes”
  • Alternative cycle routes provided
  • Temporary/permanent changes to bus stop locations
  • Bus stops that are relocated will maintain pedestrian access

*Note: Level of Service (LoS) measures operational conditions and efficiency of roads and intersections (see Appendix G, p. 68 and 69 for good summary tables of each level for both mid-block and intersection LoS). It is qualitative in that it describes mid-block conditions regarding a traffic stream and car-user perceptions of the road condition for mid-block LoS, or intersection performance given average delay for intersection LoS. LoS A = optimum operating conditions/free flow, while LoS F = a “forced breakdown in flow”, the worst condition. At LoS D or worse, actions are generally seen as necessary to resolve the problem

2 thoughts on “Traffic and Transport Construction Impacts of New M5 – Summary of AECOM’s EIS

  1. Section 1A – “The project will result in: Increased traffic along King Georges Road to the south of the M5 East Motorway, Stoney Creek Road, Bexley Road to the south of the M5 East Motorway, Harrow Road, Bay Street, Forest Road, and around the southern perimeter of Sydney Park”

    Section 1B – pt 2 Impacts to the performance of the King Georges Road Interchange
    The King Georges Road Interchange Upgrade project includes the provision of on ramps to, and off
    ramps from the New M5. The King Georges Road Interchange is expected to operate at a level of
    service F, irrespective of whether the New M5 is constructed or not.

    The results of the traffic and transport assessment undertaken for the King Georges Road
    Interchange Upgrade project (Jacobs, 2014) indicated in 2027 (10 years after opening), the
    interchange would operate at a level of service F in the AM and PM peak without the upgrade and
    with all components of the WestConnex program of works completed, as well and the future Southern
    extension. With the completion of the WestConnex program of works and the future Southern
    extension, average traffic delays at the interchange would be reduced, despite it continuing to operate
    at a level of service F.

    The New South Wales Government has committed funding to fix pinch points along key Sydney road
    corridors to improve road network performance. The pinch points program includes funding for works
    along King Georges Road at its intersection with Broadarrow Road and Stoney Creek Road. Details
    of potential upgrade works at these intersections have yet to be finalised, however it is expected any
    improvements to the operation of these intersections would likely contribute to improved performance
    of the King Georges Road Interchange.

    Which means – significantly more homes impacted with more road widening along King Georges Road.

    Even from the 1960s it was realised that you can never keep up with road demand – so best adopt what is known to work – more investment in quality and well integrated public transport.
