SH1 switch ahead

Jun 28th, 2018 | By | Category: Hot Topics, Latest News

The question of when SH1 drivers will travel along what is now a great swathe of sand beside the main road through Tamahere has been answered.

By November, SH1 traffic will divert from the current road onto the new section, which will travel under the partially built East West Link Bridge to reconnect with the existing highway near the Hamilton billboard at the top of the gully.

When traffic is switched onto the new lanes, the old highway northwest of Cherry Lane will be closed.

The sandy stretch left of SH1 will carry two lanes of traffic from around November. Old SH1 will be closed north of Cherry Lane.

The two new lanes will extend from the SH21-Airport Road Interchange, and switching traffic on to them will create room for expressway construction.

A temporary access onto the new lanes will be provided for residents of Cherry Lane, Bollard Road and the section of Cambridge Road in between.

The access point will be near the entrance to Bollard Road. For safety reasons, residents will only be able to turn left onto SH1. This means they will need to first travel south via the Airport Interchange to travel into the city.

However, residents returning home will be able to turn into the temporary access from the north and south. A right-turn bay will be provided for those approaching from the south.

    Does anyone know if they will be installing a sound barrier (concrete or wooden fence) between the properties on Vintners Lane and the Northern side of the expressway (Direction towards Hamilton)?

      I have referred your query to the contractor, City Edge Alliance, for a response.

        Julian, there are no noise walls planned in this area. The location of noise walls and earth bunds to mitigate noise is determined by a project-wide noise model that has been constructed from monitoring stations along the project. This has recently been updated to include the new 110km/hr speed limit. Where the model indicates noise may exceed the prescribed limits in Standard NZS 6806:2010 we plan noise bunds or walls to bring it within the prescribed limits. Our noise model calculates noise levels in 2041, when the interchange is expected to be operating at capacity, rather than when the Hamilton Section opens in 2020. In terms of treating everyone fairly along the project, it is important we apply the noise model consistently along the full 22km length of our project.
        If you wish to discuss your specific situation with the project team, we’re happy to meet with you. Contact us by email ( or phone 0800 322 044 and we’ll arrange a time to meet.
        FYI, the CityEdge Alliance is contracted to design and build the Hamilton Section for the NZ Transport Agency.
