Connecting the community and making it easier to get around Tinwald

People in the community tell us they want to feel safer crossing and accessing the highway on foot, by bike or when driving a vehicle.

We’re hearing that drivers using SH1 intersections are worried about crashes and are frustrated with lengthy delays at busy times.

Access from Lagmhor Road and Graham Street especially, is a challenge.

It also needs to be easier for people in the community to walk or cycle taking short journeys around Tinwald.

We’re working closely with Ashburton District Council and liaising with iwi to make changes which are designed to address the problems and improve access to the Tinwald business area, to Lake Hood and the Ashburton town centre, which is important as the Ashburton District is growing.

Key features

The main changes include:

  • Traffic signals at the SH1/Lagmhor Road/Agnes Street intersection, to make it easier for vehicles, pedestrians and cyclists to cross or turn onto the highway.
  • Encouraging traffic away from Graham Street and instead to use McMurdo St and the traffic signals at Agnes St for turning right onto the highway.
  • Changes to Melcombe Street including two-way cycle route markings (encouraging a quieter route than the highway) and intersection changes at SH1.
  • A right turn bay from SH1 onto Graham Street.
