The Princes Highway Duplication Project, Warncoort to Colac East, was a design and construct contract issued by VicRoads.
The duplication comprises of the construction of separate two-lane carriageways to provide a four-lane divided highway, with the new alignment crossing the existing alignment many times.
With all new roadwork it will address road safety, improve road capacity, improve road geometry, and provide continuity between overtaking lanes.
