Following a thorough study into collisions on the network, work will start to realign the exit and entry slip roads at Adur on Monday 7 March. Work will take place overnight, between 8pm and 6am, Monday to Friday only and is scheduled to be completed by Friday 8 April.
During the work the exit and entry slip roads will be closed in both directions, with the main carriageway of the A27 remaining unaffected.
Road users wishing to use the westbound entry slip road and eastbound exit slip road will be diverted via the Holmbush Interchange. Those wishing to use the westbound exit slip road and eastbound entry slip road will be diverted via the Lancing roundabout
By carrying out this work at night, we aim to cause the least disturbance to the road users of Sussex.
