Motorists travelling between Nelson and Blenheim could face lengthy delays after a truck rolled.
Inspector Warren Kemp said the crash happened near Hira.
He said the road is blocked and it could be sometime before the truck can be moved off the road.
Mr Kemp said the only alternative route is via State Highway Six to Murchison and then State Highway 63 to Blenheim.
