Work on re-opening Waterfall Road is expected to take up to 10 weeks.
Kāpiti Coast District Council is hopeful Waterfall Road will be open to traffic and pedestrians some time in June, after it confirmed the work is set to go ahead to fix the slip that closed the road early September last year.
Due to a risk of slope destabilisation, the road at Mackays Crossing and the bottom of Maungakotukutuku Road had to be closed for pubic safety.
Infrastructure Services Group Manager Sean Mallon says after working closely with geotechnical experts the works program was ready to get under way during last week.
Waterfall Road is the designated detour route if State Highway 1 is closed between Mackays Crossing and Poplar Avenue. There is currently no alternative route available.
The project is co-funded by NZ Transport Agency and the KCDC.
