A580 road

The A580 (officially the Liverpool–East Lancashire Road, colloquially the East Lancs) is the United Kingdom's first purpose-built A road. The road was officially opened by King George V on 18 July 1934. Despite its name, the actual road runs through the modern day metropolitan counties of Merseyside and Greater Manchester which were historically in Lancashire when the road was built until 1974. Notable towns and cities along the route include Liverpool, Kirkby, St. Helens, Leigh, Swinton and Salford. It was described as "Britain's biggest road" at the time.
