SH2 Melling Transport Improvements

As part of the Melling Transport Improvements, NZ Transport Agency (through the Delivery Alliance of AECOM and Fletcher Construction) will build a new grade-separated interchange and removing the existing Melling/Tirohanga traffic lights, among other transport improvements in Lower Hutt.
The project aims to provide better access to and from State Highway 2 and Lower Hutt, meaning less congestion and more efficient travel during peak periods, as well as improvements to safety for roads users by removing the existing conflicting right-hand turn movements.
Other benefits include:
- new and improved walking and cycling paths (including connections to Te Ara Tupua and shared paths from 4 to 4.5m wide over the SH2 and the river
- fewer pedestrian crossings to improve traffic flow and safety
- upgraded connections for Tirohanga and Harbour View communities, and
- better access to quality public transport (including relocation of the Melling train station and its park and ride facilities).

Next steps
The project remains in the Interim Project Alliance Agreement (IPAA). This is a normal practice of alliance-delivered projects that includes design reviews to identify where improvements can be made, construction planning, and opportunities to improve value for money.
The Project Alliance Agreement (the delivery contract) will be signed once the IPAA phase concludes and the final cost and construction approach is agreed.
