The Marton level crossing on Tillbridge Lane near Lincoln has been closed for two days for road resurfacing works.
The A1500 Stow Park Road is closed from Monday January 5 to Wednesday January 7, between 7am and 7pm each day.
Diversion routes are in place via the A156, A57 and B1241.
North bound traffic at Sturton by Stow should follow the B1241 towards Gainsborough.
Steve Wiles, area highways manager, said: “The work was rescheduled to avoid causing disruption on this popular route during the Christmas Market.
“The resurfacing work is necessary to improve the road surface and ensure it lasts well into the future.”
