Significant progress on the Melbourne Metro Tunnel at South Yarra has been made over the summer period, along with major road projects and tram upgrades.

Construction crews will be working until the end of January to excavate the final section of the Metro Tunnel entrance and make room for the new track which will connect the existing lines to the tunnel.

Major concreting works at the tunnel entrance will also be completed, including pouring the final sections of the tunnel roof slab and installing the tunnel support structures.

Busses have replaced trains on the Cranbourne, Pakenham and Frankston lines between Flinders Street and Caulfield Station until January 31st to accommodate the works.

Tram stop upgrades are under construction along Nicholson Street, with part of the street closed to trams and traffic until January 19th to improve accessibility of six tram stops.

The intersection of Fitzgerald and Dohertys roads in Laverton North is also closed to enable crews to rebuild the intersection, lay new asphalt and install traffic signals as part of the Western Roads Upgrade.

In addition to current projects major works will increase on the West Gate Tunnel project on January 13th. Ramps over the West Gate Freeway will be closed and rebuilt to prepare for the widening of the Westgate Freeway from eight to 12 lanes.
