What: Mulitple work crews repairing, resealing and improving the road

Where: Route 70 (Kaikoura Inland Road)

When: From 9 January 2018 to April 2018

What we are doing

You will already be aware of the huge amount of work taking place on Route 70 as we repair and improve the road. Route 70 has seen a significant increase in vehicles since the Kaikoura earthquake damaged SH1. This past winter was also a wet and snowy affair. These factors together have taken their toll on the road.

This summer we will be giving the road some well deserved attention and all this attention will mean road works and delays. It will also mean a safer, smoother ride at the end of the summer construction season. 

At the moment we have a number of crews on Route 70 doing various types of work (see over the page for more details). This week we will be wrapping up our worksites for the summer holidays ready to start again in the New Year. We expect to start work around the second week of January 2018. Generally, the only work you will see over the summer holidays will be emergency repairs or responding to incidents and accidents.

What you can expect to see more of this summer

  • Dig out/patch repairs - we cut into and dig out damaged sections of road, fill with metal, compact, and put seal over the top to waterproof the road.Speed restrictions help prevent windscreen damage from loose chip, and reduce the chances of drivers losing control on an unfinished road surface. They also help to ‘settle in’ the road surface, as travelling too fast can damage new seal.
  • Reseals - we apply layers of bitumen and chip to the existing road surface to weatherproof it again and to improve surface grip.
  • Area wide treatments where we remove the existing seal, lay metal, compact the base layers, and put some seal over the top to weatherproof the road. This work may also involve drainage work, shoulder widening etc.

Once the work is complete at a worksite i.e. the seal is down and the road is line marked, we review the temporary speed limit and may keep speed restrictions in place for a few days. Speed restrictions help prevent windscreen damage from loose chip, and reduce the chances of drivers losing control on a new road surface. They also help to ‘settle in’ the road surface, as travelling too fast can damage new seal. We then do a final sweep and remove the speed restrictions. 

Chip may continue to come loose for about a month after the work is complete so do take care while driving. We will monitor the road and sweep up chip where required.

Traffic impacts

Most of the work sites will be stop/go controlled with speed restrictions, which will mean some delays.
