Milestone for Whakawhirinaki Silverstream Water Bridge

There’s an exciting milestone coming up with the Whakawhirinaki: The Silverstream Water Bridge and Shared Path project.

 

The bridge is set to take its full form across the Hutt River in early to mid-July when the central arched steel span will be lifted into place by a 500-tonne crane. Just like the other two sections of the bridge this arch has been manufactured by a Napier fabricator and pre-assembled on site.

The central arched span will connect into the 60m section that was installed on the western side of the river in April.  Once in place the final 40m truss for the eastern side will be lifted into place to complete the bridge crossing. This huge undertaking has meant a temporary causeway is needed. It’ll be created out of the river gravel, so the massive crane can track forward while lifting the 160-tonne central arch into place.

Over the coming months, crews will be focusing on putting the permanent steel deck on the arch that will provide a pedestrian and cycling pathway before installing the new pipe. Work is proceeding at pace, and we’re pleased to say it’s on track to be completed in March 2025.
