A major route into Preston is down to one lane after a vehicle crashed into a bridge on Saturday.
AdvertisementEngineers are completing emergency repairs on the A59 Bank Bridge at Tarleton.
Lancashire County Council said an incident led to the parapet wall on the Preston bound side of the bridge having a gap left in it after being struck.
A spokesman said: “Staff have been working hard over the weekend to recover the fallen stonework so that the damaged wall can be reconstructed as soon as possible. As the bridge is a Grade II listed structure, much of the original stonework will need to be reused.
“Engineers are now working to complete the job as quickly as possible, with the bridge due to be fully reopened by Friday 14 November. Drivers are asked to consider using other routes if possible to avoid delays, particularly during peak times.”
Temporary lights are in place but traffic congestion is expected as only one lane can be used.
