Works to add new approach lanes and traffic lights at the busy roundabout are now more than halfway complete.
Cllr Richard Davies, executive member for highways, said: "Our improvements at Holdingham Roundabout are continuing to go well. In fact, we're now past the project's midway point.
"Since starting in February, the team has excavated over 4,000 tonnes of old road material to make way for new, in addition to laying over a quarter-mile of new underground drainage pipes.
"We've also had Openreach, Western Power and Anglian Water on-site to divert some of their underground services so they fit with the new design of the roundabout.
"Now that we've passed the halfway point, one of the next steps is to lay new road surfacing to the roundabout, which will involve some overnight closures. However, the details of these are still being finalised, but we will share the dates and times as soon as they're confirmed.
"In addition to that, the team will also be focusing on the new traffic signal system over the coming months, including installing wiring, setting up the system and putting over twenty new traffic signals into place.
"Once we're finished in December, people using the roundabout can expect increased safety, smoother journey and shorter travel times now and in the future in and around Sleaford."
