Western Avenue, some 10 miles (16 km) in length, is one of the major roads leading out of London. It is part of the A40, leaving the city in a north-westerly direction. The A40 is named as Western Avenue from its junction with Old Oak Common Lane in East Acton; the junction now has traffic lights, but its name Savoy Circus commemorates the roundabout which once formed the junction. East of this point is Westway, part of the A40 Central London link from Paddington. More information on the Wikipedia page [1]
