The ACT Government is delivering roads and associated infrastructure upgrades to improve access in and around the Molonglo Valley, to keep Canberra moving as we grow.
The new Molonglo River Bridge and completion of John Gorton Drive will significantly enhance connectivity across the Molonglo region and the wider Canberra road network and improving travel between the western suburbs including Denman Prospect and Whitlam.
To ensure the safety of road users, the public and on-site personnel, Coppins Crossing Road between Holborow Avenue and Hazel Hawke Avenue, will be temporarily closed in both directions from 2am on Monday 13 April to 6pm on Tuesday 14 April.
These works are subject to weather conditions, and the closure may be extended until 6pm on Wednesday 15 April, if required.
The closure is required to install concrete safety barriers, known as parapets, which will be positioned along the edge of the northbound bridge deck. These works follow the closure in March where parapets were installed on the adjacent bridge.
Further closures of Coppins Crossing Road are planned for mid‑2026 to install twin rails and throw screens to further enhance safety. Details of these closures will be provided closer to the closure dates.
During all closures, motorists are encouraged to rethink their routine, avoid travel during peak periods when possible, and plan ahead to allow extra time for their journey.
Detours for the closures are as follows:
- Southbound from Belconnen: From William Hovell Drive, take the off ramp to Parkes Way and merge onto Tuggeranong Parkway.
- Northbound from Molonglo Valley: From John Gorton Drive, turn onto Cotter Road then follow the ramp onto Tuggeranong Parkway, and take the left exit at Glenloch interchange to merge onto William Hovell Drive.
Future updates will be provided on the Build for CBR website. We thank the community for their patience, as we work to keep Canberrans, and project workers safe on-site during construction.
For details of changes to public transport during the closure, please refer to details on the Transport Canberra website at https://www.transport.act.gov.au/news/service-alerts-and-updates.
About the project
The Molonglo River Bridge project is constructing a 200-metre-long bridge across the Molonglo Nature Reserve and river, as well as 1.7 kilometres of new arterial roads leading to the bridge and two new intersections.
The new bridge, roads and intersections will provide access to the future Molonglo Town Centre from the suburb of Whitlam and future northern Molonglo Valley suburbs.
The works include important active travel links with off-road shared paths and a pedestrian underpass to encourage more Canberrans to ride or walk to get to their destination.
This project is jointly funded by the Australian and ACT Governments as part of the Commonwealth's Infrastructure Investment Program.
