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.
This stretch of the A27 between Worthing and Lancing suffers from traffic congestion which causes delays to journey times, road accidents and pollution. There is a significant amount of development planned in the area in the future and, without improvements, traffic congestion, road accidents and pollution are likely to increase. We are developing some short-term proposals to improve this section of the A27. We plan to consult on these in Autumn 2022, with work potentially starting in 2025.
