MajSC141 Mairs Bridge strengthening

Mairs Bridge #107 is situated on Westbank Road, an arterial route serving various rural properties and farmland in the Maruia area of the Buller region. The strengthening and repair works to Mairs Bridge will aim to increase the load capacity of the structure and prevent the implementation of a posting at the structure’s location. In addition, it will also upgrade and extend the working life of the structure allowing time to secure funding for a full bridge replacement.
