Sumners Road Interchange upgrade, Jamboree Heights


The Department of Transport and Main Roads has begun the detailed design for the Sumners Road Interchange upgrade.

The Sumners Road Interchange is currently operating beyond capacity, with vehicle numbers reaching 35,000 per day, and approximately 5% are heavy vehicles. 

The interchange upgrade will focus on managing the local road approaches, vehicle queuing onto the motorway and provide new active transport opportunities.

The Sumners Road Interchange upgrade will deliver a number of road network benefits, including:

  • increasing traffic capacity through the interchange
  • traffic signals that allow better management of traffic
  • safer facilities for pedestrians and cyclists with shared pathways and on-road cycle lanes, dedicated crossing facilities and links to the surrounding local network and Centenary Motorway bikeway.

The Queensland Government has committed $65 million to design and construct the Sumners Road Interchange upgrade.

In September 2018 the design for the SRIU was announced and will include the following:

  • new signalised intersections that will replace the existing roundabouts
  • a new 2-lane eastbound bridge
  • the existing westbound bridge will be demolished and in its place a new 4-lane bridge will be built with provisions for pedestrians and active transport users
