Project Value: $9.2 million

Project Description

The 13 month project comprised the realignment of Great Eastern Highway around the Clackline town site and the construction of overtaking lanes North of Bakers Hill, involving extensive clearing and earthworks. The contract also included the upgrade of intersections and the installation of roadway lighting and signage in the highly trafficked area. Highway Construction also realigned a heritage trail and constructed a precast concrete underpass on the trail.

Clackline Brook was realigned and a major box culvert was installed on this culturally significant site for Aborigines. The excavation of a borrow area adjacent to the highway was subsequently rehabilitated and landscaped.

Special Features/Challenges: 
  • Heavily trafficked semi-urban area required complex traffic management 
  • Extensive rock gabion protection for major culvert 
  • Drill and blast over 3,500m3 adjacent to Great Eastern Highway 
  • Protection of heritage areas and the environmentally sensitive Clackline Brook. 
  • Construction of a 2 x 2400 x 2400 box culvert in Clackline Brooke.
