Wembley Road Interchange

The current interchange

The current interchange is at capacity. There is regular congestion, causing traffic to queue back onto the Logan Motorway and Wembley Road, in both directions.

The existing interchange has a two lane roundabout at Illaweena Street, which all traffic use no matter the direction of travel. The existing roundabout becomes congested with a mix of traffic trying to exit and enter the Logan Motorway, or travel through to Wembley Road.

This includes a large volume of freight vehicles, which worsens congestion as trucks often need to use both lanes on the roundabout to negotiate the turn.

Two lanes along Wembley Road from Greenfern Drive to Pagewood Street, including the bridge across the Logan Motorway, restricts through traffic along Wembley Road.

Restricted turning lanes to and from the Logan Motorway westbound on and off-ramps restrict traffic movements both to and from these ramps and along Wembley Road.

The solution

The final concept design for this interchange will improve safety and reliability, reduce travel times and the amount of traffic on local streets, enhance connectivity to key residential and business areas, and cater for future growth.

Community and stakeholder feedback has directly shaped the final concept design for this interchange:

  • widening Wembley Road to four lanes between Greenfern Drive and Pagewood Street, including replacing the two lane bridge over the Logan Motorway with a new four lane bridge (doubling capacity)
  • removing the Illaweena Street roundabout and replacing it with a signalised T-intersection
  • relocating the Logan Motorway westbound on and off-ramps and upgrading Anderson Street to include a signalised intersection at Wembley Road with additional and extended turning bays
  • adding additional stormwater culverts under Wembley Road and raising Wembley Road to reduce flooding impacts.
