Matakitaki River, Murchison

Project Info

Client TDC and NZTA

Project Description

The Matakitaki river works is a joint TDC and NZTA job to protect the SH6 bridge over the Matakitaki river and decrease the impact on surrounding areas during flood events in Murchison. We are into our third week with over 15,000m3 of river gravel already moved out of the channel. Along with an estimated 78,000m3 volume of gravel to be removed from the river more than 5000ton of rock is to be placed in the channel for bank protection. Rock rip rap protection walls will be constructed under both ends of the bridge to protect the bridge abutments. Spur groynes will also be placed on both banks upstream to help direct the river under the centre of the SH6 bridge.
