Strathallan Street-Portsmouth Drive Intersection Opens For TrafficWork to improve safety and traffic flows at the Strathallan Street-Portsmouth Drive-Wharf Street intersection is complete and upgraded traffic signals will be operational from tomorrow. This will create more capacity and improve traffic flow on Strathallan Street. Traffic can turn right onto Portsmouth Drive from Orari Street or Midland Street intersections. Car parks along Strathallan Street were removed to accommodate the dual approach lanes, both east bound and west bound, near the Portsmouth Drive intersection. The Strathallan Street-Portsmouth Drive-Wharf Street intersection improvements are a key part of the wider Harbour Arterial project, running from the Caversham Motorway (SH1)/Andersons Bay Road intersection through Andersons Bay Road, Strathallan Street, Wharf Street, Thomas Burns Street, Ward Street and the Ward Street overbridge.
