Work will start this week on a scheme to widen the A16 near Clay Lake in Spalding in order to build a new right-hand turn lane.
A new road will also be built to connect the A16 to the industrial estate at Clay Lake.
The £450,000 scheme will provide a link to a new industrial estate that’s being developed on a site of a former poultry farm.
The work is being funded by Ashley King Developments, as part of a wider investment in Spalding and the surrounding area.
The changes will accommodate an increase in traffic into the site, and enable easier access from the A16 into the nearby Clay Lake housing development.
The works are set to start on Sunday and will last for 13 weeks, with completion set for November 14.
Two-way traffic movements will be maintained on the A16, but the lane widths will be narrower and a 40mph speed limit in place.
There will be a one-night lane closure at the start of the project and a three-night lane closure towards the end.
Councillor Richard Davies, executive member for highways at Lincolnshire County Council, said: “This is the first stage in a much welcomed investment from Ashley King Developments, which will lead to new jobs and business growth in the area.
“Motorists on the A16 shouldn’t be too inconvenienced by the work we’re doing.
“We’re narrowing the lanes and introducing a 40mph speed limit and, aside from a couple of night-time closures, two-way traffic will be maintained at all times.

John Walton at Ashley King Developments, said: “This project represents an exciting opportunity for us as a local based developer to reinvest back into the community.”
