A section of the A120 in Braintree will be closed for three nights next week as part of a road improvement scheme.
The road will be closed in both directions between the Panners Interchange, Great Notley, and Galleys Corner, between 8pm and 6am on Monday, Tuesday and Wednesday nights.
Resurfacing and road marking work will be carried out during this time.
Diversions will be in place in both directions via the A12.
A Highways Agency spokesman said: “The roundabout improvements, which are due for completion later this month, are aimed at increasing capacity around the roundabout, to reduce congestion on the A120 westbound approach to the junction.
“Drivers and residents are thanked for their patience during this work.”
