Grange Road, Holbrooks Road and East Avenue Intersection Upgrade

About the project

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.

Project timing

Over the coming months, early works will continue as part of the planning works. Localised demolition activities will also occur during this time to make room for the new road alignment. We will keep you up to date and nearby residents will be notified prior to any demolition activities commencing.

Major construction is anticipated to commence in early 2025, with the intersection expected to open to traffic in late 2025.
