A127 road

The A127, also known as the Southend Arterial Road, is a major road in London and Essex, England. It was constructed as a new arterial road project in the 1920s, linking London with Southend-on-Sea, replacing the older A13. Formerly classified as a trunk road, it was "de-trunked" in 1997. It is known as the Southend Arterial Road except for part of its length in Southend-on-Sea. It is also streetlit for its whole length despite its majority coverage through rural land.

Route

The A127 starts as a turning off the A12 at Gallows Corner in the London Borough of Havering. Traffic heading towards London goes over a flyover and joins the A12 traffic which merges onto the slip-road from the roundabout below, which is where the A127 ends. Traffic heading towards Southend also uses the flyover as well as slip roads. Its first significant junction is a crossroads after ¹⁄₂ mile (0.80 km) (Squirrels Heath) with Squirrels Heath Road and Ardleigh Green Road. There are traffic lights here, but after that, there are no traffic lights or roundabouts until it enters Southend-on-Sea, though there are a few side turnings. Major junctions follow the layout similar to motorways, being served by high-level or low-level roundabouts accessed via slip roads.
