Drivers faced lengthy diversions after railway barriers malfunctioned and blocked a busy A-road.
The barriers on the A1075 between Watton and Thetford were stuck in the down position, forcing drivers travelling in both directions to turn around and seek alternative routes.
Engineers from Network Rail were at the crossing in an attempt to repair the fault, while officers from Norfolk police assisted and advised motorists.
The barriers were fixed and began working later on Monday afternoon.
