Temporary traffic lights are expected to be in place at a busy Lewes junction for the next two weeks.
The move comes after the existing lights were hit by a car.
The incident happened on Sunday (February 17) on the A26 Malling Hill / Malling Down, at its junction with Church Lane and Mill Road.
The traffic light controller, which controls the phasing of the lights, a power supply pillar and street light column were destroyed.
East Sussex Highways is working to build a new controller and replace the damaged columns. The work is expected to take around a fortnight.
