A lorry crash on the B1190 at Doddington has caused a road closure and delays on Thursday morning.
The DAF lorry, which was fully loaded with stones, slid off the road while travelling over the bridge.
Nobody was injured in the incident, which was reported to police at 7.35am on January 23.
One lane is open and police are directing traffic. The B1190 between the A46 and A57 will need to be closed for recovery, but police hope to do this once the A46 at Lincoln re-opens.
It is one of several incidents causing traffic chaos this morning, including a section of the A46 being closed after a transporter lorry overturned on Wednesday night.
