Motorists in Sheffield are being warned about a 20-week prohect to strengthen the bridge over the Tinsley canal, near Meadowhall.
Work on the bridge, which forms a link between the Meadowhall area and M1 motorway, is due to get underway on Monday.
During the project the bridge will remain open in both directions, with outbound lane closures and lane narrowing to inbound traffic in place.
Steve Robinson, Head of Highway Maintenance for Sheffield City Council, said: “We have many old, beautiful and historic bridges across the city. To ensure that we keep them for residents, commuters and visitors to the city to use for years to come, we need to take care of them.
“We are aware that by carrying out the repairs we will inconvenience commuters, but hopefully they will understand that this vital work needs to take place.”
Andrew Harley, Structures Manager for the city’s Streets Ahead project, which will see all Sheffield’s roads improved over the next two decades, said: “It’s important that we strengthen Tinsley Canal Bridge now to eliminate the risk of additional maintenance issues and increased traffic delays in the future.”
