Sealing complete on Matangi Road

The road approaches to the Matangi Road Bridge have now been sealed. Line marking and sign installation will follow. Excavation of the expressway under the bridge will begin shortly.

Next, our pavement team will seal the Osborne Road Bridge approaches at Horsham Downs.

Building our longest bridge

Construction of the Hamilton’s section’s longest bridge is progressing well. The Mangaonua Gully Bridge is 150m long, and is the only steel bridge on the project.

The photos show the wing wall panels that were precast on the ground, then lifted into place by crane. Wing walls provide support for the road foundations where they tie in with the bridge structure.

Beams heading our way

We’re about to place the bridge beams at two interchange bridges – Greenhill and Ruakura. The beams have been manufactured in Auckland and will be delivered one-at-a-time by a special truck and jinker (rear steering unit), then lifted into place by cranes.

Underpass passes the test

We’ve built a stock underpass near the Greenhill Interchange to allow stock to be moved from one side of the expressway to the other. The photo shows our fencing contractor proving the underpass design is a perfect fit for a farm tractor.

Installing services at Kay Road

Installing a water main under a bridge deck 15 metres off the ground is a challenge. The video below shows how our contractors used a roller system to push and pull a new water main under the Kay Road Bridge, then fix it in place. Mission accomplished!
