All northbound lanes have reopened on the M1 Pacific Motorway in Ewingsdale after an earlier car crash approaching St Helena Tunnel.
The diversion via Hinterland Way and Myocum Road has been lifted.
Emergency services and traffic crews were on site working to free a trapped person.
Northbound traffic on the motorway remains heavy so motorists are advised to allow additional travel time as conditions return to normal.
