A safety project to install a new median barrier at the Maungatapu bridge will begin next Tuesday.
The NZ Transport Agency announced this morning the work will take about two months to complete.
Transport Agency highways manager Brett Gliddon said the project formed part of a suite of safety projects it was looking after along the sections of State Highway 29 from the Maungatapu bridge to the summit of the Kaimai Ranges.
"The changes are designed to improve safety along this stretch of highway and to make it a more forgiving environment for drivers," Mr Gliddon said.
The work forms part of the Government's Safer Journeys strategy and uses the Safe System approach which aims to reduce death and serious injury on high risk sections of the highway by improving the roads and roadsides.
