M1 Motorway Upgrade (Weakleys Drive and John Renshaw Drive Intersection)

Project Description: The upgrade involved the replacement of the existing roundabout intersection with traffic lights to improve traffic flow, travel times and motorist safety.

Full scope of works for the project includes:

• the replacement of the roundabout with traffic lights;
• construction of two through lanes on all approaches;
• construction of additional turning lanes on all approaches, including two right turn lanes from the motorway to John Renshaw Drive;
• the extension of the two northbound lanes on Weakleys Drive from the traffic lights to Enterprise Drive;
• the upgrade of the existing left-turn slip lane from John Renshaw Drive to the motorway;
• the addition of a new left-turn lane from John Renshaw Drive to the motorway; and
• additional on-road provisions for cyclists.

The project is a part of RMS’ M1 Productivity Package ($391.6 million) funded by the Federal and NSW State governments to improve overall traffic flow and safety on the M1.
