Mt Messenger Bypass

Great journeys connect people and places and enable us to move goods and services safely and efficiently. 

The Mt Messenger Bypass on State Highway 3 (SH3) is planned to deliver better road safety, resilience and journey experience.

It is 5.2km long with additional work at the southern end creating about 6km of improvements and runs east of the existing highway (identified as Option C in the June 2017 public engagement). It includes a bridge about 110m long and an estimated 230m long tunnel under the ridgeline south-east of Mt Messenger. A consents process is underway and construction is expected to occur during 2019–2022.

 

Who we are

The Mt Messenger Alliance brings together the NZ Transport Agency, Downer, HEB Construction, Tonkin & Taylor, WSP Opus, Holmes Consulting and Isthmus.

Collectively we bring national and international experience in infrastructure development.

Our team is made up of transport designers, engineers with geometric, geotechnical, structural and construction expertise, RMA planners and environmental specialists including ecologists, landscape architects and stakeholder and communication professionals.

Our work

We carried out a consultation to gauge the views of the public and other stakeholders  in 2016/17 about three route options for Mt Messenger. Community participation was high and while feedback strongly supported one of the bypass routes [PDF, 9.4 MB], concerns about its environmental and cultural impacts were raised. In June 2017 we provided an update on route options, which included five proposed routes.

In August 2017 a new bypass route was selected.(external link) It is located east of SH3 [JPG, 748 KB]
