Decmil was awarded the construction of a new multi-span bridge over the Princes Freeway (Sand Road) and the construction of a full diamond interchange at Longwarry for VicRoads.

The Sand Road Interchange Project (the Project) was a significant safety upgrade for the section of the Princes Freeway, which was one of Victoria’s most dangerous black spots. In the period between 2000 and 2015, three fatalities, several serious injuries and 60 casualty crashes were recorded at the intersection as “cross traffic” collisions or when vehicles were turning at the intersection.

The Project involved the construction of a new multi-span bridge over the Princes Freeway (Sand Road), single span bridges for Ramps B and D traversing the Thompson’s Drain, design and construction of temporary Sand Road deviation for traffic access to Princes Freeway East and the construction of two roundabouts on Sand Road to complete the full diamond interchange, at Longwarry making travel safer, easier and faster for road users between Gippsland and Melbourne along the Princes Freeway.

The collaborative framework approach adopted by VicRoads and Decmil focused the parties on ensuring issues were resolved on a ’Best for Project’ basis, which ultimately delivered on improved amenity outcomes; enhanced safety; reduced traffic impacts; and significant time efficiencies and cost savings.

Throughout the Project VicRoads were very complimentary of the Decmil team and the manner in which we delivered the Project, which was acknowledged by VicRoads rating Decmil 9 out of 10 for ‘Cooperative Relationships’, in the Contractor Performance Report dated 11 April 2016.
Delivered eight weeks ahead of time, with the final cost 4% ($700K) under the original contract budget, road users accessing the Longwarry and Labertouche communities are no longer required to pass across fast moving freeway traffic, whilst improving traffic flows vastly increased efficiencies for freight and industry operators.

Delivering solutions.

We are committed to outstanding project management and delivery regardless of the scale or the intricacy of the work.
