Next month, the RiverLink team will start investigations to better understand the geotechnical complexities of the Hutt Valley. This work will inform the design of the new stopbanks, a large retaining wall which will support the promenade, piers and abutments for the pedestrian cycle bridge and help us understand the costs for building a highway interchange and new Melling bridge. We also expect the findings to help us understand how a nearby major fault line could impact our designs and how best to protect the aquifer beneath the surface.
From August to October 2018 you can expect to see all manner of machinery both in and around the river. We’ll use excavators, drill rigs and other geophysics equipment – all in accordance with resource consent conditions. This work will take place on both sides of the river from just upstream of Melling Bridge to the Ewen Bridge. The enclosed map shows where the work will be done.
At some locations, there will at times be limited access to the river. There will be traffic management in place along Daly Street and the Melling railway station carpark while work is done at these locations. More details about what to expect will be available closer to the time.

Since 2014, the Transport Agency, HCC and Greater Wellington Regional Council (GWRC) have worked collaboratively on a RiverLink programme which involves three separate but interdependent projects – flood protection improvements, the Making Places urban development plan and the Melling transport improvements.
The RiverLink programme seeks to identify a coordinated investment programme to improve flood protection along the Hutt River, provide better urban amenity connections between the Hutt city centre and the Hutt River and improve the transport connections at Melling.
