Northconnex

The Northconnex project will connect the M2 and M1 through a 9km tunnel which runs under Pennant Hills Road in order to alleviate traffic and create a more seamless route heading north out of Sydney. At 14 work locations, WS+P has co-ordinated the adjustment of all Sydney Water infrastructure works to accommodate the installation of the tunnel, the four (4) vent shafts and each of the site compounds.

Marsh St, Westconnex

As part of the Westconnex amplification, an extra lane will be added to Marsh Street to accommodate incoming traffic flow. A number of Sydney Water assets will be affected by these works. The works require a sewer main running parallel to Marsh Street to be adjusted for the bridge extension works. The bridge extension will run over a DN1800 trunk main from the desalination plant, which will also require supervision during construction.
