Planning and development is well underway to upgrade Tonkin Highway south of Roe Highway. The project includes widening Tonkin Highway from four to six lanes and upgrading the intersections at Hale Road, Welshpool Road and Kelvin Road, improving safety and reducing delays along this heavily congested route. 

This important project will be delivered under two contracts. The first will include the intersections along Tonkin Highway at Hale Road and Welshpool Road, and the second includes Tonkin Highway and Kelvin Road.
