About the project

This section of SH1 forms part of the country’s most important transport corridor between Auckland-Hamilton-Tauranga which accounts for a significant proportion of all road freight in New Zealand.

To make this stretch of road safer, flexible median barriers will be installed to reduce the amount of serious crashes along this section of state highway.

The safety improvements will be delivered in two stages. Stage 1 improvements will install 2.4km of flexible median barrier, and Stage 2 will address key safety risks on 4.5km of the highway.

Key features and timeline

Stage 1: Install 2.4km of flexible median safety barrier from south of Fergusson Gully to a nearby reserve. Waka Kotahi anticipates work starting in August/September, weather dependent, with about eight weeks of construction. There has been a slight delay as we have needed to investigate the integrity of the existing shoulder seal to ensure it is durable enough to carry the state highway traffic during the construction phase. 

Stage 2: Will address key safety risks on 4.5km of the state highway from the reserve to Maungatautari Road. Our preferred design for this work will be available soon, and we are currently planning opportunities to discuss this with the community.  The design will then be finalised, and any construction is anticipated to be in 2021.
