Hanger Lane gyratory

It enables intersection with the North Circular (A406) and the inceptive Ealing Road towards Wembley.

[1] An above-ground section of the London Underground Central line passes under the structure which takes the form of a rounded-corner rectangular roundabout.

The south-east corner of its interior hosts Hanger Lane tube station accessed by paths beneath; the rest hosts small utility buildings and a nature reserve which has many mature, deciduous trees – a Site of Importance for Nature Conservation.

[2] In the 1960s, a 240 metres (260 yd) long tunnel was built to take the A40 road underneath the Hanger Lane junction.

[4] Before its tunnelling cost was approved, the High Speed 2 railway was to cause a remodelling of the gyratory,[1] 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.
