Six tennis court lengths of road will be resurfaced every night as work starts today (July 6) on the A1 near Leeds.
Motorists face delays as sections of the work, which includes replacement of road markings, studs and general maintenance, will be carried out at Boston Spa and Braham.
About 1,2000 sq metres of road will be resurfaced as part of the work on the A1 which will last for three months in total.
Highways England said there will be a 50mph speed limit on the southbound A1 from Junction 45 at Boston Spa to Junction 44 at Braham until July 28.
Work will then take place on the link road connecting the A64 westbound carriageway with the southbound A1 at Braham crossroads.
The section of the link road will also have a 50mph speed limit between July 28 and September 4.
Project manager Daniel Edwards said: “This resurfacing work will replace the worn out carriageway making the road safer and smoother to travel along.
“We would ask drivers to drive carefully and follow the clearly signed diversion routes for the duration of this work.”
