Roadworks at A52 near Horbling will cause diversions on A15, A151, A16, A17 and Kings Road near Bourne
Night-time resurfacing works on the A52 near Horbling will start on Monday (March 8).
The work, between Swaton Lane and South Forty Foot Drain Bridge, is expected to last for four weeks, Monday to Friday.
A night-time road closure will be in place on the A52 and B1177 near Horbling from 7pm to 6am each weekday.
The diversion route will be via A52 / A15 / A151 / King Road / A151 / A16 / A17 / A52, and vice versa.
Access for emergency vehicles will be maintained as far as reasonably practicable throughout the works.
Karen Cassar, assistant director - highways, said: "As part of these works, we will be rebuilding a 1.5 mile section of the A52 near Horbling that is deteriorating and in need of repair.
"We intend to do everything we can to minimise disruption, including carrying the works out overnight and doing our very best to maintain access for nearby residents during the works.
"We ask for your continued patience while these works are carried out.
"Once complete, these improvements will make travelling the A52, one of our county's busiest roads, safer and more comfortable for all road users."
