Roadworks on one of the busiest stretches of road in Brigg began on November 30 and it was initially thought they would conclude yesterday (December 11).
However, drivers are being advised that the roadworks on Wrawby Road will continue until 11.59pm on Tuesday (December 15).
Anglian Water is responsible for the A18 works which involve the deployment of temporary traffic lights on the A18 near Beldon House.
Use of the footpath on that side of Wrawby Road has been suspended during the contract.
