Asphalt surfacing at the Walnut Avenue traffic lights work site will disrupt traffic through the area this weekend, and next week, Waka Kotahi is advising Ashburton residents.

The intersection of Walnut Avenue and East Street will be closed during the day from 7am to 7pm on Sunday 20 March to complete asphalt surfacing on that piece of road.

The work can only be done if the weather is dry and warm, so if conditions are poor the work may move to Monday 21 March.

There will be no vehicle access in or out of the intersection, though footpath access will be maintained.

Then from Monday 21 March for about five days, an asphalt top coat on West Street will be laid. The work will take place between 7am and 7pm, and two-way traffic will be maintained on West Street, however traffic lanes will shift location as needed.

This work will result in Walnut Avenue West, Queens Drive, and the rail crossing being closed day and night while the work is done.

Detours will be in place and a 30km/h speed limit in place.

This is a Waka Kotahi project to replace two roundabouts with traffic lights.
