After Easter, permanent repairs begin on the SH25 underslip at Opoutere.
From Tuesday, April 11 contractors will begin earthworks to create benching below the road to get machinery into the location to build a retaining wall.
There will be no major impacts on traffic over the next fortnight. Light vehicles (boat trailers and caravans are okay) can still use the temporary diversion track, Waka Kotahi says.
Road users should expect road closures of up the 30 minutes between 9.30am and 2.30pm on weekdays so avoid travelling at this time if you can.
The work is expected to take seven weeks to complete so the road should be back to full functionality for both heavy and light vehicles by the end of May.
Elsewhere around Coromandel these holidays – road users will see contractors working between Ruamahunga and Tapu on a 40-metre-long rock fill site. Work will be ongoing here for around three weeks.
People are urged to check the Waka Kotahi Journey Planner before they travel and be prepared to wait.
