This project by has achieved an 'Excellent' As Built v1.2 IS Rating.
Overview
The Gateway Upgrade North project was jointly funded by the Australian Government ($914.18 million) and Queensland Government ($228.54 million) on an 80:20 split. Lendlease was contracted to design and construct the project, on behalf of the Department of Transport and Main Roads, who were assisted by Transurban Queensland. Major works commenced in early 2016 and the project’s completion was announced in March 2019.
The project delivered safety and efficiency improvements on the Gateway Motorway between Nudgee and Bracken Ridge; a four-lane section of motorway providing a critical transport corridor for more than 83,000 vehicles each day. The extra traffic lanes constructed on the motorway and the Deagon Deviation are significantly reducing traffic congestion, and improving traffic flow, travel time reliability and driver safety. Key improvements to this section of the motorway involved the following scope of works:
- widening the motorway from four to six lanes between Nudgee and Deagon
- undertaking safety improvements on the motorway between Deagon andBracken Ridge
- reconfiguring the Nudgee Road interchange, including constructing a new Nudgee Road overpass
- widening the Deagon Deviation between Depot Road and Bracken Ridge Road to provide two lanes in each direction
- modifying the Bicentennial Road interchange, including extended on and off- ramps
- constructing a new northbound bridge over Sandgate Road and the Shorncliffe rail line and widening the existing southbound bridge
- constructing an off-road cycle/pedestrian facility
- installing Intelligent Transport Systems including variable speed limit signage,variable messaging signs, traffic monitoring cameras and ramp metering.

Rating Highlights
Procurement and Purchasing
Pro-3: Lendlease’s procurement process enabled all potential suppliers, (not just supply agreement contracts) to be evaluated using the Lendlease Letting Approval form which has a 40% Non-Commercial weighting prior to acceptance. This then led to an environment and sustainability score given for each contractor. This scoring is completed based on the responses provided as part of the pre-qualification questionnaire and tender interview process.
Pro-4: All contracts with Lendlease requests that suppliers provide data to assist the project in achieving sustainability targets and objectives. Monitoring against these targets occurred throughout the entire project. Examples of targets as linked to commitments in the project sustainability policy which suppliers are requested to provide data against include:
- - Reductions in project delivery carbon emissions which is primarily managed through NGERs data collection
- - Reduction of virgin material use
- - Create sustainable jobs through traineeships and apprentices
Discharges to Air, Land and Water
Dis-1: There are four creek catchments, drains that pass through and also wetlands which sit adjacent to the Project. Evidence demonstrated that no adverse impacts have occurred in these Creek catchments during the construction phase. The final Issued For Construction Design Report for Longitudinal Drainage confirmed that the proposed reductions in hydraulic parameter loads of Total Suspended Solids, Total phosphorous, Total nitrogen, and gross pollutants have been achieved. The levels of reduction achieved were very high which is attributable to the project drainage design incorporating water quality control devices. This has resulted in the demonstration of an improvement to receiving water environmental values.
Dis-3: The project work has not caused physical damage to any buildings or structures.
Dis-4: The project demonstrated no exceedances of air quality goals.
Heritage
Aboriginal cultural heritage values within and adjacent to the project were identified, considered and addressed and acknowledges the whole project area to be of significant to the Turrbal people regardless of whether on a register or not.
The interpretative signage at the rest stops installed along the shared user path, contained detail to promote the local heritage values. As an example, the installed interpretative signage at Nudgee Road Interchange rest stop included some information around the traditional language, local history and information of the area.
The historical survey tree near to the Deagon Depot site office was identified for preservation throughout the construction period, with the site office and deck constructed with an Arborist onsite prior to screw piling to check the location of the tree’s roots.
The design for the Nudgee Interchange has included advanced stock trees of culturally-significant Bunya Pines. The trees will curl off the end of the bridge in a circular pattern as part of a wider land art design, which is inspired by the highly culturally significant Nudgee Water Hole and Bora Ring.
