allow removal of an overhead gantry at Dairy Flat.
Both north and southbound lanes of the motorway will be closed between Oteha Valley Road and Silverdale from 10:00PM
until 5:00AM. On ramps at Oteha Valley Road and Silverdale will close at 9:00PM. A detour via the Dairy Flat Highway
will be signposted, says Waka Kotahi Auckland System Manager Andrea Williamson.
