Waione Street Bridge

About

The Waione Street Bridge (also known as the Hutt Estuary Bridge) is a bridge across the Hutt River in Lower Hutt, New Zealand that was completed in 1954. The bridge is notable because it was the first substantial bridge in New Zealand to be constructed using prestressed concrete beams. The bridge connects Petone with Seaview, and carries Waione Street with one lane in each direction. It also carries major water pipes across the Hutt River. There is a pedestrian walkway on the south side. The bridge has 5 main spans, each of 32 m (105 ft) length, supported with four piers installed into the bed of the river. The foundations of the bridge are unusual, because the piers are bedded on a layer of marine clay that overlies the Waiwhetu artesian aquifer.
