Hanger Lane gyratory

The Hanger Lane gyratory is a large, complex roundabout system at the junction of Western Avenue (A40), the North Circular (A406) and Hanger Lane in the borough of Ealing in west London. It covers an area of about 30,000 square metres (320,000 sq ft). At rush hour it carries nearly 10,000 vehicles per hour. An above-ground section of the London Underground Central line passes under the roundabout. The island in the middle contains Hanger Lane tube station and a nature reserve (Site of Importance for Nature Conservation).

In December 2007 it was named Britain's scariest junction.

The junction became a gyratory system in the early 1980s when the western side of the loop was built. It originally was to have to be replaced for the construction of the High Speed 2 railway line, but in April 2013 it was decided to put this section of HS2 in a bored tunnel instead due to the cost of rebuilding the gyratory system.
