The A153 between Tattershall and Billinghay has now re-opened after the county council completed repair work on a large sinkhole.
As previously reported, the road was closed on April 9 and re-opened later that day with temporary traffic lights, but it was fully closed again on April 14 after the condition of the road deteriorated.
It was closed due to a partially collapsed culvert just south of Tattershall Bridge.
The county council was forced to warn people against ignoring road signs and abusing the workers during the closure, describing it as “unacceptable”.
The council confirmed that it re-opened the A153 at around 5.30pm on Tuesday, April 28 after repairs had been completed.
Councillor Richard Davies, executive member for highways at Lincolnshire County Council, said: “We’ve reopened the A153 between Tattershall and Billinghay. Thank you to local residents for bearing with us, and to the team for their hard work repairing the road.”
