Cunningham Highway (Ipswich - Warwick), Eight Mile intersection upgrade

An overpass is being built at the Cunningham and New England highways intersection, to improve safety.

The Eight Mile intersection is a significant crossroad located 8miles (or 12.87km) north of Warwick where the Cunningham and New England highways meet. It is a major rural intersection for traffic between Brisbane, Warwick and Toowoomba.

The project involves building an overpass for motorists travelling south from Toowoomba to Warwick. Other traffic movements at the intersection will remain at ground level which will be upgraded to improve safety and efficiency. Traffic on the Cunningham Highway will travel underneath the overpass.
