Dogleg removed in crucial upgrade

Wednesday, 27 September 2023

A frustrating western suburbs ‘dogleg’ intersection will be removed, saving commuters time and improving safety in a newly unveiled concept plan for a key route across Grange Road at Beverley.

Holbrooks Road and East Avenue will be re-aligned in the $90 million upgrade, one of a suite of enhancements to intersections near the River Torrens to Darlington Project that will collectively ensure the Adelaide road network functions efficiently, both during construction of the project and once it is completed.

The upgrade will improve traffic flow for a key parallel route to South Road during construction of the T2D Project and in the longer term, by creating two new through lanes in each direction directly linking Holbrooks Road and East Avenue.

The intersection upgrade will also include:

• two dedicated right-turn lanes for traffic going from Grange Road onto Holbrooks Road travelling south;
• two through lanes on Grange Road travelling east and one through lane plus a shared through-and-left on Grange Road travelling west;
• a dedicated left-turn lane from Grange Road onto East Avenue travelling north;
• two dedicated right-turn lanes from East Avenue onto Grange Road travelling west;
• a left-turn slip lane from East Avenue onto Grange Road travelling east;
• two dedicated right-turn lanes from Holbrooks Road onto Grange Road travelling east; and
• a left turn slip lane from Holbrooks Road onto Grange Road travelling west.

The upgrade includes improvements to pedestrian safety by re-aligning the existing three pedestrian crossing points to four pedestrian crossings with two pedestrian refuge crossing points.

Cycling safety will also be improved via the introduction of dedicated intersection entry and exit cycle lanes.

Other intersection improvements will include new LED road lighting, asphalt, drainage, kerbing and gutters.

Main works are scheduled to commence in late 2024, with the project expected to open to traffic in late 2025.

The Department for Infrastructure and Transport will hold community information sessions in the coming weeks for people to give feedback on the concept map and ask questions of the project team.

Works have already begun on other broader network upgrades linked to the T2D project, including the Selgar Avenue link road at Tonsley and resurfacing works along South Road. The upgrades, collectively valued at a total of $850 million as part of the broader $15.4 billion North South Corridor completion, will collectively support 300 jobs a year during construction.
