Design

The original Gateway Upgrade North Preferred Plan was released to the public in October 2013.

Key features of the project’s design include:

  • widening the motorway from four to six lanes from Nudgee to Deagon
  • reconfiguring the Nudgee interchange including a new Nudgee Road overpass
  • widening the Deagon Deviation between Depot Road and Bracken Ridge Road to provide two lanes in each direction
  • modifications to the Bicentennial Road interchange including extended on and off-ramps
  • construction of off-road cycle/pedestrian facilities
  • Intelligent Transport Systems including variable speed limit signage, variable messaging signs, traffic monitoring cameras and ramp metering.

As a result of the intensive tender process, a number of key innovations have been made to improve the Preferred Plan, including:

  • future proofing the motorway by making allowance for the six lane upgrade to be widened to eight lanes in the future, accommodating forecasted traffic increases and population growth
  • incorporating an off-road pedestrian and bicycle path along the entire length of the project with covered rest areas and a new pedestrian and cycle connection over Sandgate Road and the Shorncliffe rail line – read more about active transport
  • constructing a new northbound bridge over Sandgate Road and the Shorncliffe rail line to replace the existing bridge and avoid long term maintenance issues
  • improved outcomes for the Deagon Racecourse – under the Preferred Plan the racetrack had to be realigned, however under the revised design the track will be unaffected and only the starting chute will be relocated
  • significantly reduced impact to the Deagon Wetlands
  • relocation of the motorway ramps to and from the upgraded Deagon Deviation to improve safety outcomes and increase capacity – read more about the upgraded Deagon Deviation
  • rehabilitation of the Gateway Motorway between Bracken Ridge and the Bruce Highway including pavement and safety improvements.
