Gateway Upgrade North (GUN) & Rocklea to Darra (R2D)
This week we joined in celebrating two Queensland road projects achieving Excellent Ratings in their IS Scheme certifications. The event was organised by Queensland’s Department of Transport and Main Roads (TMR) in recognition of the great work undertaken on the Gateway Upgrade North (As Built IS Excellent Rating) and the Ipswich Motorway Upgrade Rocklea to Darra Stage 1 (IS Design Excellent Rating).
These projects demonstrate Queensland’s commitment to long term sustainability and resilience, reinforced by the State Infrastructure Plan which requires all state government projects valued at more than $100 million to assess sustainability using Infrastructure Sustainability Council of Australia’s Infrastructure Sustainability Rating Scheme or the Green Building Council of Australia's Green Star rating tool.

The projects also showcase some Australian firsts under the IS Scheme’s Innovation Category. This includes the largest reported use, by volume, to date, of EME2 pavement (high modulus asphalt) by the Gateway Upgrade North Project, which will result in a more sustainable use of non-renewable pavement materials. They also pioneered a Glider Pole Crossing which is suspended between steel light poles rather than conventional timber pole, improving ecological outcomes. The Rocklea to Darra Project features an alternative design for short-span bridges resulting to 57% reduction in concrete and 54% reduction in the stressing required for the bridges.
Congratulations to the significant stakeholders involved including: TMR, Transurban Queensland, Lendlease Engineering Pty Ltd, Bielby Holdings, JF Hull & Albem Joint Venture and Losee Consulting.
