These works are coordinated alongside closures at Dome Valley to ensure as much work as possible can be done under these closures, to minimise disruption.
The works will involve laying the final road surface, chipseal, barrier installation, line marking, signage and more.
Road layout changes may be required in the south to complete the final tie-in works around the Johnstone Hill Tunnels. Waka Kotahi will provide an update on this work when more information is available.
Completion of these works brings us closer to opening the new motorway which will provide a safer, more resilient and reliable road with more consistent travel times. Based on current progress Waka Kotahi anticipates that NX2 and their subcontractor Fletcher/Acciona Joint Venture will be in a position to open the road in the second quarter of 2023.
While all efforts have been made to limit disruption to traffic flows, we encourage you to plan your journey over this time and check the Waka Kotahi Journey Planner before heading out.
