With the design process already underway, the upgrade of Sumners Road Interchange moves one step closer to completion.

The Queensland Government Department of Transport and Main Roads recently awarded the design contract to Arup Consultancy in March 2018. The department plans to start early works sometime in late 2018.

Member for Mount Ommaney Jess Pugh is delighted that the project is moving forward.

“This is great news for people who travel through western Brisbane because it will ultimately mean less time spent in the car, and more time spent doing what they enjoy,” said Ms Pugh.

The project is part of the $65-million allocation to decongest Sumners Road Interchange and Centenary Motorway, which registered some of the slowest traffic speed during peak hours, according to a report by RACQ.

The upgrade project is much anticipated as Sumners Road continues to operate beyond its capacity. Every day, up to 35,000 motorists pass through the interchange. Five-percent of the vehicles using the interchange are heavy vehicles.

Decongesting traffic flow at Sumners Road Interchange is essential as it is the main interchange going to the Ipswich-Centenary Motorway intersection. The project would also ease connectivity to Darra train station by reducing bus travel time.

The plan includes adding a second overpass bridge at Sumners Road. This is intended to improve the traffic flow along the interchange. The design will also replace roundabouts at each end of the bridge with signalised intersections.

On-road cycle lanes, shared paths and dedicated crossing facilities will also be added to encourage active transport options.

Once the project is completed, it should improve efficiency and reliability for public, private and freight vehicles passing through the interchange. The project also aims to promote the safety of active transport commuters.

The upgrade is projected to take around three years, weather and construction conditions permitting.
