The A127, also known as the Southend Arterial Road, is a major road in Essex, England. It was constructed as a new arterial road project in the 1920s, linking Romford 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.
