Metro Tunnel
The Metro Tunnel (sometimes also known as the Melbourne Metro Rail Project or the Metro Rail Capacity Project) is a metropolitan rail infrastructure project currently under construction in Melbourne, Australia. It includes the construction of twin 9-kilometre rail tunnels between South Kensington station (north west of the Melbourne City Centre) and South Yarra (in the south east) with five new underground stations. The southern portal for the tunnel is to be located to the south of South Yarra station. As a result, the tunnel will connect the Pakenham and Cranbourne lines with the Sunbury line, and allow these lines to bypass Flinders Street station and the City Loop while still stopping in the Melbourne central business district.
West Gate Tunnel
The West Gate Tunnel, originally known as the Western Distributor, is a 5 kilometre toll road currently under construction in Melbourne, Australia, to link the West Gate Freeway at Yarraville with the Port of Melbourne and CityLink at Docklands via twin tunnels beneath Yarraville. The $5.5 billion project was proposed by infrastructure company Transurban in 2014 as a means of alleviating congestion on the M1 corridor, providing a new river crossing as an alternative to the West Gate Bridge and moving trucks away from homes in the city's inner west. The freeway-standard link includes two tunnels with three lanes each that are approximately 4 km long outbound and 2.8 km long inbound, a new bridge over the Maribyrnong River, and an elevated road above Footscray Road. The project will also widen the West Gate Freeway from 8 to 12 lanes between the M80 Ring Road and the West Gate Bridge. The Victorian government announced in December 2015 it would proceed with the project. Major construction of the tunnel and elevated tollway began in January 2018 and is expected to be completed in 2022.
