As the only east-west trunk road south of the M25, the A27 serves a population of more than 750,000 people, and connects a number of coastal communities between Portsmouth and Pevensey, near Eastbourne.
Safety is a problem throughout the A27 corridor where there are frequent accidents and incidents. There are also few crossing points for pedestrians, cyclists and horse riders, and poor east-west connections.
That’s why we’re making a number of improvements along the A27 which will mean the road is safer and more serviceable, more accessible and integrated as well as more free-flowing.
As the main road serving the south coast, the A27 is a crucial route through the south east. However, as it passes through Arundel it operates well over capacity and causes disruption and severe congestion. Highways England is therefore developing options for how the route could be improved.
The A27 to the east of Lewes suffers from congestion due to the narrow carriageway and low capacity at junctions. There are limited overtaking opportunities, meaning that traffic regularly queues behind cyclists and other slow moving vehicles.
The scheme is currently under review. The Worthing and Lancing section of the A27 lacks road and junction capacity. As a result it suffers from congestion, particularly at Grove Lodge, Durrington Cemetery and Lyons Way.
