Work is currently programmed from 10 March until the end of May. The works are located on the A23 between its junctions with Patcham Interchange and the B2117 to the north of Brighton.
The work will all be carried out overnight and involve carriageway and lane closures. It is expected to be completed on the morning of Thursday 17 April.
These works are additional to the “major improvements” to the A23 that local readers will already be very familiar with.
