Dundee motorists are set to face major traffic disruption on the A92 for the next four weeks.
The project got under way on Sunday and is involving surfacing works across three locations between Claypotts junction and Elliot roundabout at Arbroath.
Eddie Ross, operating company representative for BEAR Scotland, said the work was “essential to ensure the continued safe use of this stretch of the A92”.
Project bosses have tried to ensure there will be minimum disruption to road users with work taking place overnight between 7pm-7am, Sunday-Friday.
No work will take place on Friday and Saturday nights.
During the operation sections of the A92 will be closed overnight with traffic diverted locally.
The majority of the project will take place using a 10mph convoy system to keep road users as well as motorists safe. Any diversions will be signed in advance.
Bus services will follow diversion routes, with stops within the closure area unavailable during those periods.
Phase one started between Upper Victoria and Ardestie interchange at Woodhill westbound, and Ardestie interchange bridge.
Work being carried out by Tayside Contracts will mean traffic being diverted south from Upper Victoria Interchange on to the C1 Carnoustie Road, the A930 Barry Bypass to the B962 Newbigging Road, the B961 Drumsturdy Road to C4 Ethiebeaton to West Grange Roundabout and on to the A92.
On Sunday and Tuesday nights works will start with the on-slip closure from 7pm, and a 10mph convoy working on the dual carriageway.
On Monday and Wednesday nights the slip road will be re-opened, however a 10mph convoy system will remain in place.
During the closures traffic will be diverted to the B962 Newbigging Road, the B961 Drumsturdy Road to C4 Ethiebeaton, the West Grange Roundabout and on to the A92.
BEAR Scotland will be supervising work being carried out.
Mr Ross said: “We will do everything possible to keep disruption to a minimum and have planned the project to take place overnight as well as avoiding the busier Friday and Saturday nights.”
