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 remove 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).
