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.
Victoria Park Tunnel
The tunnel, to initially cost approximately NZ$440 million (2009 estimate), later corrected down to $340 million, is a northbound-traffic carrying structure only, entering the ground in the area of the existing 'Birdcage' heritage pub (which will be relocated to allow the tunnel portal to be built in the area), and reemerges to the northwest of the park where it feeds into additional lanes provided alongside the St Marys Bay stretch of the motorway. The tunnel provides three lanes of traffic, and is 440 m long. Construction was originally to last four years, starting in January 2010, after the new National government fast-tracked further state highways investment.
