More Waikato bridges are set for strengthening, enabling the expanding use of ‘high productivity motor vehicles’ (HPMVs).
The NZ Transport Agency says work on three bridges along State Highway 1 between Tirau and Putaruru are set for modification – the Oraka Stream bridge, just south of Tirau, the Oraka Stream Bridge at the northern entrance to Putaruru and the rail over-bridge just south of Putaruru.
Along State Highway 3, between Te Awamutu and Awakino, work will be carried out on the Mangapiko Stream bridge just north of Te Awamutu, the Mangaorongo Stream bridge near KioKio Station Road, and the Mangaotaki River bridge, 15kms south of Piopio.
The bridge strengthening works form part of a national programme by the Transport Agency aimed at opening up more key HPMV routes.
