Upgrading of High Street between Carrington Street and Stirling Highway is underway and will improve safety and reduce congestion along High Street.
Works include the construction of a new roundabout at the intersection of High Street and Stirling Highway and a wide median on High Street to separate traffic lanes.
New underpasses will also be constructed at the junctions of Forrest Street and Stirling Highway, and Montreal Street and High Street.
Temporary roundabout at the intersection High Street and Stirling Highway
As part of the High Street Upgrade, a temporary roundabout now replaces the signalised High Street and Stirling Highway intersection to enable the safe and efficient construction of the permanent roundabout.
The temporary roundabout will:
- enable fewer disruptive traffic switches for the remainder of the project, minimising driver confusion and improving safety; and
- provide construction access to larger sections of the intersection, to help build the permanent roundabout more efficiently.
As more of the permanent roundabout is constructed, traffic will be moved to the new sections in stages, until the permanent roundabout is commissioned in mid-2021.
Comprehensive pedestrian and cyclist detours will also be required to construct and implement the temporary roundabout and build the new permanent roundabout.
As the road layout may be unfamiliar, please drive with care and follow the signage provided.
