Motorists in West Sussex are advised to allow extra time to travel on the A27 whilst an exit slip road remains closed.
It follows damage to a bridge parapet and safety barrier following a single vehicle collision at the weekend (June 16) on the westbound carriageway of the A27 Shoreham bypass.
The closure of the exit slip road for the A283 for Shoreham is expected to remain for around four weeks, for safety reasons, whilst a temporary barrier is in place.
The month-long closure is due to the time it takes for the replacement made-to-measure permanent safety barrier to be manufactured.
National Highways are advising drivers to plan ahead, allow more time for their journeys, and to find alternative routes if at all possible.
Further updates on the timescales for repair will be shared as they are confirmed via National Highways X feed, @HighwaysSEAST and the National Highways: South-East Facebook page.
