Transport for NSW has recently completed improvements to the intersection of Princes Highway and Railway Road at Sydenham.

Project information

The NSW Government funded this project as part of its $300 million Gateway to the South Pinch Points Program, which aims to reduce congestion and improve travel time on Sydney’s key southern corridors.

When our roads are busiest there are delays turning from Railway Road onto the Princes Highway at Sydenham. To fix this, we have upgraded this intersection by adding a new right turning lane and by moving the Princes Highway pedestrian crossing taking pressure off this local ‘pinch point’.

Up to 700 vehicles an hour turn from Railway Road onto the Princes Highway. Long queues and delays of more than four minutes are common in the busiest periods. To get traffic moving we have widened Railway Road to create two dedicated right turning lanes onto the Princes Highway and maintained the existing dedicated left turning lane. We have also moved the pedestrian crossing on the Princes Highway to the other side of Railway Road. Motorists turning right will no longer have to wait for pedestrians to cross the road before they can turn. We have also adjusted the traffic light phasing to give more time to the busiest parts of the intersection.

This project will:

  • Improve travel times by up to 12 hours a year for people who use this road each day when our roads are at their busiest.
  • Reduce congestion and improve traffic flow by widening Railway Road to create dual right turning lanes and maintain the current dedicated left turning lane.
  • Upgrade the pedestrian crossings and adjust the traffic light phasing to give more time each green light to the busiest parts of the intersection.
  • Improve safety for pedestrians and road users.

Pinch points are traffic congestion points, intersections or short lengths of road at which a traffic bottleneck exists slowing down the broader network. They cause a build up of traffic and travel delays at these spots and on the wider road network.

Roads and Maritime asked for your feedback in April 2017. We received comments from nine people and have responded to all community feedback in a consultation report. We thank everyone for considering the proposal and for the time they spent to give us feedback.
