Rebuild of State Highway 1 Maromaku getting underway


The NZ Transport Agency says work to repair the Maromaku slip on State Highway 1, south of Kawakawa is reaching road level this week.

Motorists will soon see contractors beginning to build the stabilised-earth retaining wall which will support the newly rebuilt road which was damaged during severe flooding in July last year.

The Transport Agency’s Safety and Network Performance Manager, Tim Crow says improved drainage and new safety barriers will make the highway, which is being built along the pre-flooding alignment, safer and more resilient.

“Additional culverts are being installed across and adjacent to the road to improve drainage and make the road more stable.”

“Now that road workers have moved up the hill and will be working at the same levels as vehicles we ask all those travelling through this section of the state highway to take extra care and stick to the 30 km speed limit, to keep everyone including road users and workers safer,” says Mr Crow.

“The road layout will also change as a new safety barriers are installed and the route is moved from the temporary deviation back on to the newly repaired road.”

The seal on the road surface during this final construction phase will be uneven prior to the final seal being laid.

Contractors will continue to work on site between 7am and 6pm, seven days a week to get the repairs finished. The work is weather dependent.

The NZ Transport Agency apologises for any disruption to people’s journeys and thanks everyone for their ongoing patience as we work to make this stretch of the highway safer and more resilient.
