Ahead of the upcoming closure of State Highway 1 (SH1) Brynderwyn Hills for critical restoration work, NZ Transport Agency Waka Kotahi (NZTA) has been working with our partners to ensure detour routes are as safe and as high quality as possible for people and goods.
All detour routes are progressing well and are on schedule for the closure on Monday 26 February.
Steve Mutton, Director Regional Relationships NZTA says that crews have been preparing SH12 and SH14 for heavy vehicles while working closely with the Northland Transportation Alliance on local detour routes for light vehicles including Cove Road and Paparoa Oakleigh Road.
High productivity motor vehicles (HPMV) must use SH12/14, which is also the suggested detour route for heavy vehicles.
Local detour routes via Cove Road or Paparoa Oakleigh Road are recommended for light vehicles.
“We recognise these detours will take longer, especially for freight, which is why we will be working as quickly as possible to carry out this important work.
“We encourage people to use it as an opportunity to explore Northland and have an adventure while travelling along the scenic routes.
“The suggested detour via SH12 and SH14 offers some great places to stop along the way and the Cove Road route provides a great opportunity to take a break and enjoy beaches on their travels” says Mr Mutton.
People are also urged to drive to the conditions over the summer and keep a lookout for our roadworkers still hard at work over the break.
