Project updates


West Melton is a growing residential area west of Christchurch. In addition to the tavern and community centre on this stretch of highway, there are also several intersections as well as increasing numbers of homes. As part of the review of speed limits, a number of safety concerns were identified, including the safety of pedestrians crossing SH73 and the safety of cyclists using the highway.

We talked to the community, council, local businesses and others about making the highway in West Melton safer. We have had some feedback from the community that people were travelling too fast through this community.

Investigation and evidence

When determining the proposed speed limit that we consulted on, we reviewed the speeds that people are currently driving on this road, as well as the road itself. The speed limit of 60km/h was assessed to be the safe and appropriate speed limit for this road.

Crash history

In the 10-year period between 2009 and 2018, there 14 crashes, one of them causing injury.

Travel times

The new permanent speed limit will have minimal impact on travel times. Over the 970 metre distance, the increase in travel time will be approximately eight seconds.
