Delays are expected on the A17 on Friday while urgent repair works are carried out.
Karen Cassar, assistant director – highways, said: “The traffic barrier on the bridge’s westbound carriageway was destroyed on Wednesday evening when a vehicle collided with it.
“Luckily, no one was seriously injured in the collision and the ship passing through wasn’t delayed – thanks to quick reactions from the bridge operators.
“Our plan is to replace the broken barrier tomorrow so it’s ready to use next time the bridge needs to be opened.
“Unfortunately, we’ll need to close the westbound-side of the bridge while we carry out these works. This is to ensure the safety of road users and our workforce.”
The repair works will start at 9:30am and last for up to five hours.
Temporary traffic signals will be in place on the bridge during these times.
An alternative route is advised via Wisbech on the A1101 and A47, back to the A17.
Karen added: “We encourage anyone planning to use the A17 between 9:30am and 2:30pm on Friday to leave extra time for their journeys as there will very likely be delays.
“I want to thank everyone in advance for their patience while we carry out these emergency repairs.”
