Grange Road, Holbrooks Road and East Avenue Intersection Upgrade

The Department for Infrastructure and Transport is upgrading the intersection of Grange Road, Holbrooks Road and East Avenue to relieve congestion and improve safety and connectivity for all road users at this location.

The upgrade will remove a staggered intersection and create a direct connection across Grange Road between Holbrooks Road and East Avenue. This project, being delivered as part of an $850 million suite of projects is designed to ensure Adelaide’s road network functions efficiently during construction of the River Torrens to Darlington (T2D) Project, and once it has been completed.

Concept design

What else is planned

Pedestrian and cyclists

The upgrade includes improvements to pedestrian safety by installing four new pedestrian crossings with two refuge crossing points.

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

Public Transport

The upgrade will improve access for bus services around the intersection.

Community engagement

Thank you to everyone who attended one of our community information sessions and who shared their local insights via the project survey.

The survey has now closed, and we look forward to sharing what we heard in early 2024.

Project timing

Ground investigation works and site preparation works, including site clearing activities will be undertaken over the coming months.

Other early works including services activities are anticipated to commence in early 2024.

Major construction is scheduled to commence in late 2024, with the intersection open to traffic in late 2025, weather permitting.
