Heavy traffic is anticipated in Lincoln this weekend due to planned road closures for maintenance, diverted trains and seasonal events.
The closure of Lindum Hill will continue this weekend from 7am on Saturday in both directions while maintenance takes place.
The County Council says it will be reopened as soon as possible to ease congestion.
At the same time, Network Rail will divert up to 50 northbound trains from the East Coast Mainline through Lincoln for the next four weekends.
The diversions are being caused by repairs on the line near Grantham. This means train barriers will be down for a longer amount of time than usual.
Lindum Hill is currently undergoing nine-day resurfacing and reconstruction due to last winter’s bad weather ruining the road surface.
Diversions have been put in place for motorists to go downhill via Yarborough Road, and uphill from Broadgate along Monks Road or Clasketgate.
Thousands are also expected to descend upon the city for the University of Lincoln’s open day for prospective students and the annual Sausage Festival.
Area Highways Manager Mark Welsh said: “We do anticipate that these highways improvements together with the train diversions will cause some disruption this weekend and we’d urge people to plan their journeys carefully and follow the diversions.”
