The Melbourne Metro Tunnel’s eastern entrance structure has been completed more than five months ahead of schedule.

Works are now underway to connect the structure at South Yarra, to the project’s twin tunnels.

In September one of the project’s tunnel boring machines broke through at South Yarra after completing its journey from Anzac Station .

The creation of the eastern entrance structure has been two years in the making.

It included widening the existing rail corridor, excavating more than 31,000 cubic metres of earth, and building a base slab, internal walls and roof slab using more than 7,700 cubic metres of concrete and almost 8,000 tonnes of reinforced steel.

All four tunnel boring machines on the project are now continuing to dig parts of the project’s twin 9 kilometre tunnels.

Three quarters of tunneling on the project is now complete.
