Drivers who use the Northern Motorway should be aware of layout changes to the southbound lanes between Oteha Valley Road and Greville Road, starting next week.

The changes will be put in place overnight this Sunday 10 April and require a full closure of State Highway 1 in both directions (between Oteha Valley Road and Greville Road) while the temporary lane barriers are installed.

The closure will go from Sunday 8pm – 5am Monday morning. Detours via Hugh Green Drive for southbound travel and Albany Express for northbound travel will be in place for those travelling overnight on Sunday 10 April.

From Monday morning the left-hand lane will become an off-ramp only for people wanting to leave the motorway at Greville Road. Drivers continuing their journey south towards the city are advised to use the two right-hand lanes.

The layout changes are required in order to continue works on the Northern Corridor Improvements project.  

The changes will be in place for the next few months along with a reduced speed limit of 80km per hour to allow the team safer entry and exit to the work area in the middle of the motorway.

When complete, the Northern Corridor Improvements project will provide a suite of transport upgrades for the Auckland region. The Northern Busway will be extended from Constellation Station to Albany Station and new direct motorway connections between SH1 and SH18 will open up access to the Western Ring Route and airport. The project will also deliver more than 7km of shared paths and local connections for people travelling on foot or by bike.
