Rail services on the line through Stamford Oakham are to resume after an accident.
The Foster Bridge in Ketton was hit by a lorry on November 5, causing the rail line to be closed.
Since then, buses have replaced rail services between Leicester and Peterborough, but travel is expected to return to normal in both directions on Wednesday (23 November).
Oakham drivers should expect much longer delays at city crossings on Saturday (November 19) and are urged to avoid them.
Essential freight services were able to cross the damaged bridge, but using a ‘one-way’ system.
The A6121 Stamford Road, which passes under Foster Bridge, is not expected to reopen until 6pm on Friday November 25.
Gary Walsh, East Midlands Route Director for Network Rail, said: “It has been a huge job for our teams and I am delighted that the line between Leicester and Peterborough will fully reopen next Wednesday.
“The damage to Ketton Bridge was extensive and we are truly sorry for the impact this has caused.
“Our teams have worked hard to complete these repairs as quickly as possible and I would like to thank passengers and the local community for their patience.
“In the meantime, passengers should continue to check before traveling and Oakham-area drivers should avoid city crossings where possible on Saturday.”
John Robson, East Midlands and East Anglia regional manager for CrossCountry, said: “We look forward to being able to run our services as normal again and are delighted with how efficiently Network Rail has been able to restore services following the impact substantial damage to the bridge.
“We would like to echo Network Rail in thanking the local community and our customers for their patience.”
