Oxford Street, Shopping street in West End, England

Oxford Street is a major road in the City of Westminster, running about 1.2 miles (1.9 km) from Marble Arch to St Giles Circus via Oxford Circus. It is Europe's busiest shopping street, with around 300 shops as of 2012. The street is lined with pale stone buildings, and red double-decker buses fill the roadway; a round red-and-white sign marks Oxford Circus.

The route follows the Roman Via Trinobantina, later Tyburn Road, where prisoners were carted from Newgate to the Tyburn gallows until 1783. A turnpike trust was set up in 1721, and after the Earl of Oxford bought surrounding fields the road was renamed Oxford Street by about 1729. Selfridges opened in 1909, and John Lewis was rebuilt in the 1950s after wartime bombing.

The name comes from an old route that once led to the university town, and today shopfronts line both sides while buses and taxis roll past the pavement. People stream into windows, sit on benches between entrances, and wait at crossings that set the rhythm of the street.

Several Underground stations lie along the route, including Oxford Circus, Bond Street, Tottenham Court Road and Marble Arch, all offering access to the shops. The street is heavily used during the day, so it can be easier to visit early morning or late evening when fewer people are around.

Oxford Street is part of the A40, the trunk road from London to Fishguard, though no sign on the street shows that number. Since the 1970s private cars have been barred during weekday and Saturday daytime hours, leaving the roadway to buses and taxis.
