As part of its ongoing Three Waters capital works programme, a new water main will be laid along State Highway 88, starting from Roseneath and extending towards St Leonards.
This project will connect to work completed earlier this year to install a new water main to the West Harbour community.
The contract for this stage has been awarded to McConnell Dowell.
Construction will begin near District Rd in Roseneath and progress along SH88 to about Wren Lane in St Leonards.
The council is working closely with NZ Transport Agency Waka Kotahi and Port Otago to co-ordinate the project.
While there will be no direct impact on access to individual properties, the wider West Harbour community and all traffic to and from Port Chalmers will be affected.
Excluding public holidays and the Christmas break, SH88 will be reduced to one lane at all times.
The first stage of work begins next Monday and is expected to take up to 10 weeks.
During this period, District Rd will be temporarily closed.
Access to Roseneath will remain available via Shandon Rd, including for public transport.
Detour signage and reduced speed limits will be in place to support the diversion.
The full project is expected to be finished by June next year.
Council Three Waters group manager John McAndrew acknowledged the disruption the work might cause for West Harbour residents, businesses and other users of SH88.
"This project is a vital investment in our city’s infrastructure, ensuring the continued delivery of high-quality drinking water for years to come." — Allied Media
