Ring Road - Wairere Dr Extension

Overnight road closure on Cobham Drive

State Highway 1 Cobham Drive will be closed to southbound traffic between Galloway Street and Cambridge Road for 10 nights from Sunday 26 September (weather dependant).

The closure will be in place from 7pm to 6am each night, with traffic diverted along Galloway Street and Naylor Street/Cambridge Road. Northbound traffic will remain on Cobham Drive.

The closure is to allow for work to take place on the southbound lanes at the intersection of Galloway Street and Cobham Drive. 

As always we appreciate your patience while we do this work.

What's happening now?

Currently, most of our work is happening in the centre of the site, to construct the Cobham Drive overbridge. This includes:

  • Construction of the 17 columns which you can see in the above image. These were completed in April.
  • We are now starting work on the scaffolding, which will provide a safe working area for us to construct the bridge pier.
  • We are also working on the retaining walls by the northbound off ramp and the northern embankment.
  • Structural fill is currently being put in place for the bridge approaches. We are reusing fill from the temporary road.

In the coming months there will be some impressive work happening, including planting over 40,000 plants and 350 trees, completing the retaining walls, and placing the bridge beams. Thanks heaps for your patience while we work hard to shape a city that's easy to live in.

​​​​​​​​​​​​​​​​What is the Ring Road?

Once completed the final piece of the Hamilton Ring Road, the extension of Wairere Drive between Cambridge Road and Cobham Drive will connect the future bridge over the Waikato River into Peacocke. To do this Cobham Drive will be raised to allow the four-laned Wairere Drive to pass underneath it. Work will also include extensions of shared walking and biking paths for people to enjoy.

The total project cost to build the final section of the Ring Road is $45M, of which 75% is contributed by the government through Waka Kotahi NZ Transport Agency subsidies. 

Completion anticipated early 2022.​

Below is a 3D visualisation concept video of how the final section of the Hamilton Ring Road will look once completed.
