Gateway Upgrade North

Our Role

As part of a design joint venture, SMEC delivered the project’s design including detailed design of all elements, geotechnical investigation management, temporary traffic design, and construction phase support.

Key considerations during the design included:

1. Managing high volumes of traffic on an existing motorway

2. Widening an existing motorway over soft soils and sensitive environment

3. Innovation in delivery to minimise adverse impact on road users.

Project Overview

In August 2014, it was announced that Transurban Queensland (formerly Queensland Motorways) would oversee procurement of the major construction contract for the Gateway Upgrade North project on behalf of the State Government. The $1.143 billion upgrade project is funded by the Australian Government and Queensland Government and includes:

  • Widening of the motorway from four to six lanes from Nudgee to Deagon.
  • Reconfiguring the Nudgee Road 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.
  • Installation of Intelligent Transport Systems including variable speed limit signage, variable messaging signs, traffic monitoring cameras and ramp metering.


The Gateway Upgrade North project was completed and officially opened in March 2019. Commuters will see a reduction in peak hour delays, increased safety measures and capacity to cater for projected increases in passenger and commercial vehicle usage. We are proud of the work the SMEC team delivered under the SMEC and Jacobs Design Joint Venture. Our partnership and strong collaboration translated into an outstanding solution.
