WORK began on Thursday to resurface the A303 east of Andover.
The work will be carried out overnight until the morning of Wednesday, 9 July, on the A303 between the A34 at Bullington Cross and Micheldever Station.
Guy Watts, Highways Agency project sponsor, said: “The work will involve the complete resurfacing of the A303 in both directions, providing a new smoother road surface for drivers and maintaining safety by improving skid resistance.
“To minimise disruption we have planned work to take place overnight, when traffic flows are at their lowest, and a clearly signed diversion will be in place so that drivers can continue their journeys.”
Work will take place between 10pm and 6am with no work over weekends.
From yesterday, work is taking place on the eastbound carriageway for eight nights. This will then be followed by work on the westbound carriageway for 15 nights from Tuesday, 10 June, returning onto the eastbound carriageway for six nights from Tuesday, 1 July.
During the work, the A303 will be closed in one direction at a time between the A34 and M3.
Road users travelling westbound will be directed to continue on the M3 to junction 9 or south on the A33 to access the A34 northbound, rejoining the A303 westbound at Bullington Cross.
Road users travelling eastbound will be diverted onto the A34 at Bullington Cross to rejoin the M3 at junction 9.
