20-28 Chalmers Street entrance to Central Walk is a new underground pedestrian concourse at Central Station that will better connect transport passengers to trains, light rail and the new Sydney Metro underground platforms.

As part of continued improvement by the NSW Government to upgrade infrastructure, Central Walk includes:

  • a 19-metre-wide tunnel from Chalmers Street linking to new Sydney Metro platforms under Central
  • new, easy access points to Sydney Trains platforms 16 to 23
  • escalators directly to suburban platforms for the first time.

The entry at Chalmers Street will provide direct access to Central Station for customers from the Surry Hills catchment area and a direct interchange for passengers from the CBD and South-East Light Rail.

In conjunction with design and construction teams, Penetron Admix was chosen to provide extensive waterproofing and durability to key structures in this area. Penecrete Mortar was used to treat all coil tie-bolt holes within the capping-beam
