State Highway 1 north of Kaikoura, Mangamaunu to Clarence is now back in action after a truck became stuck at the single lane section of Waipapa Bay.
However, people should expect some delays while the backlog clears and take their time.
New Zealand Transport Agency journey manager Tresca Forester said "The truck tipped over but remained upright and stuck on State Highway 1 before 3pm today."
Picton to Christchurch traffic was being redirected at each end onto the alternate route, which is the Lewis Pass.
SH1 through Kaikoura is due to close tonight at 8.30pm and will reopen at 7am tomorrow.
