The New Merrimac Station is the third train station to be delivered under the Cross River Rail Delivery Authority. This will be located on Gooding Drive, approximately 750 metres east of the Pacific Motorway and Gooding Drive Interchange (Exit 77)
The Station will include:
• Two new 155m long side high-level platforms with 220m space allowance for future extension to accommodate a 9-car train.
• An overhead pedestrian footbridge connecting both sides of the station and platforms, including the provision of passenger lifts (DDA compliant – through lifts) from each side.
• Stair access to be provided to the pedestrian footbridge, for both access and egress from the site.
• Replacement of overhead electrical gantries throughout the new station.
• New station car parking facilities with DDA bays, taxi bays, kiss n ride bays, and bus stop and layover bays connected to Merrimac Station.
• A new signalised three-way intersection provided at the junction of Gooding Drive.
Stage 1 of the Alkimos Seawater Desalination Plant (ASDP) will deliver a plant capable of producing 50GL/a of water supply to Perth and Peel region, which in the future will have the potential to expand to 100GL/a (Stage 2). Together with the Eglinton Groundwater Scheme, also to be delivered by 2028 (4.9 GL/a), these two major water sources will produce an estimated combined capacity of ~105GL/a. Due to the location of the site in Alkimos, the seawater desalination plant will require a Trunk Main to deliver the source water to the closest Integrated Water Supply Scheme (IWSS) large storage facility in Wanneroo known as the Wanneroo Reservoir. To enable the integration of the new water source into the IWSS, it is proposed that a 32.5km Trunk Main (TM) is installed from ASDP to Wanneroo Reservoir with an offtake to Carabooda Tank. The first 6km of the 32.5km ASDP TM is commenced delivery in early 2022. This project is to deliver the remainder and majority of the 32.5km connection.
The Project proposes signalised intersections on Waihoehoe Road at Great South Road and Kath Henry Lane. The Waihoehoe Bridge over the North Island Main Trunk (NIMT) is proposed to be reconstructed offline to provide for the widened carriageway cross section including an active mode corridor and raised to allow sufficient space underneath for future rail upgrades (electrification and future rail tracks). To the west, the Project will tie into existing Norrie and Great South Roads, and to the east, the Project will tie into existing Waihoehoe Road at the Kath Henry Lane and Drury Central Station (DCS) access intersection. The functional intent for the upgrade, in line with the Project objectives, is to provide a strategic link that provides access to the planned Drury East housing development area and connects the DCS and associated park and ride facilities, forming a key public transport and active mode spine.
Boundary Road (Coopers Plains) rail level crossing project is being delivered by the TMR, and funded by the Australian Government (AG), Queensland Government (QG), and Brisbane City Council (BCC).
Boundary Road (Coopers Plains) is a BCC controlled road which connects to Beaudesert Road and acts as a key east-west link between Archerfield and the M1 Gateway Motorway. The primary objective of this project is to improve the safety and congestion of the existing road-rail level crossing on Boundary Road at Coopers Plains.
At the level crossing, Boundary Road (Coopers Plains) crosses the Beenleigh and Gold Coast Rail Lines, which consists of three tracks. The number of scheduled trains per 24-hour period is approximately 202 resulting in significant boom gate downtime during morning and afternoon peak periods.
The Boundary Road level crossing has consistently been named as one of Queensland’s top 10 worst level crossings from train drivers’ perspectives in TrackSafe’s 2013 survey and has been identified in multiple reports as a high-risk level crossing with recommendations for removal, including:
• 2012 Deloitte – Boundary Road in top six high risk priority crossings
• 2019 Queensland Rail ALCAM (Australian Level Crossing Assessment Model) – identified Boundary Road in the top 3 most dangerous crossings in Queensland
• 28 boom strikes (2009 – 2016) the third highest rate during this time period
• 101 incidents at the site (2004-2011
The project will remove the existing level crossing at Boundary Road by providing a new overpass over the rail corridor and provide an elevated three-way intersection connecting Boundary Road and Orange Grove Road.
• 1.7 km of dual carriageway arterial road
• 2 signalised intersections
• 3 span, 227m dual carriageway bridge with ability to accommodate light rail in the future
• Weathering steel box girders with a concrete deck
• Steel encased concrete piers with piled abutments
• Includes shared path access into adjacent development and river corridor, on-road cycle lanes and provision for public transport (bus stops)
The South Gippsland Highway level crossing impedes the flow of 31,000 cars and trucks each weekday, with boom gates down for a third of the two-hour morning peak.
The Victorian Government announced the removal of this crossing in November 2018 as one of 25 additional new crossings to be removed. The final design solution was confirmed as road over rail.
Major works began in mid-2020, with the road bridge completed in just over a year and opened to traffic in late 2021
The project scope also includes 8000 square metres of green space, which will be constructed at the site of the former intersection of South Gippsland Highway and Princes Highway. This area will include additional sections of shared use path, seating and lighting.
The South Gippsland Highway level crossing removal project was completed in Mid 2022.
