The Humber Bridge is to close overnight to enable vital maintenance work to take place.
The work includes changing two bearings at the Hessle Tower and will be carried out overnight one weekend in September/October, although the actual date will be dependent on the weather.
The same bearings at the Barton Tower were replaced last October when the bridge also closed for a night.
The bearings connect the bridge deck to the towers and help carry the weight of the bridge and traffic whilst also allowing the bridge to move in response to the wind and temperature.
They are being replaced because after more than 40 years of use, they have come to the end of their working life.
Andrew Arundel, Chief Operating Officer at the Humber Bridge, said: “Changing the bearings is a routine maintenance operation, but it is a significant undertaking that requires the road deck to be jacked up so the new bearings can be fitted into place.
“Therefore, it is not possible to have traffic using the bridge while the work is being carried out.
“The bridge will close late on a Saturday evening and is forecast to open again by 9am the next morning, ensuring the minimum possible disruption for bridge users.
“We also have a contingency plan in place for any emergency vehicles that need to use the bridge during the hours that it is closed.”
Mr Arundel added that replacing the bearings at the Barton Tower had gone smoothly and the work had finished ahead of time.
“As long as the weather remains okay, we anticipate the work will go according to plan and the bridge will only be closed for a short period of time,” he said.
The precise date of the work will be confirmed in due course and announced on the Humber Bridge website and social media.
