Victoria’s Big Build will heat up over summer, with major works on four regional train lines, the West Gate Bridge and the City Loop as crews continue to transform the state’s road and rail network.

Annual maintenance works will close four outbound lanes on the West Gate Bridge between Boxing Day and Wednesday, 4 January 2023. With only one outbound lane open on the bridge, drivers are advised to detour early.

Significant delays of more than 90 minutes are expected across Melbourne including on the West Gate Freeway between the city and the West Gate Bridge, as well as the Domain Tunnel, Monash Freeway and throughout the CBD.

From 9pm on Monday, 2 January 2023 through to the last service on Sunday, 15 January 2023, crews will work around-the-clock in the City Loop to upgrade smoke detection, extraction and sprinkler systems at Flagstaff, Melbourne Central and Parliament stations. This work is being undertaken while the network has the lowest expected patronage.

Flagstaff, Melbourne Central and Parliament stations will be closed, and no trains will run through the City Loop throughout the works. Southern Cross and Flinders Street stations will remain open, with trains running to and from these stations.
