由於維修的連帶影響，貨運服務不得不以 "錯誤的方向 "通過該鎮。
Repairs to a railway bridge that was struck by a lorry are making "good progress" and train services are set to resume next week, Network Rail says.
A section of the A6121 on Stamford Road, which the bridge crosses, is expected to reopen to traffic on 25 November at 18:00 GMT at the earliest.
Gary Walsh, East Midlands route director for Network Rail, said: "This has been a massive piece of work for our teams and I am pleased the line between Leicester and Peterborough will fully reopen next Wednesday.
"The damage to the bridge at Ketton was substantial and we are very sorry for the impact this has caused."
Freight services have had to travel in the "wrong direction" through the town, due to the knock-on effects of the repairs.
Essential planned engineering work on the Crossrail route on this day means freight traffic will need to travel through Oakham and the level crossing barriers in the town will be down for much longer than usual.
