The Transport Agency says a crash on Auckland's southern motorway is causing major delays in both directions, just before rush hour begins.
Police say a ute and trailer rolled just south of the Newmarket Viaduct, on the north-bound side, just before 2pm on Friday.
The crash is blocking two out of three north-bound lanes and debris is also blocking the south-bound lanes.
The Transport Agency says there are considerable delays in both directions and drivers should use other routes.
