Chiswick flyover

The Chiswick flyover is a short elevated section of the M4 motorway in the western approaches to London, United Kingdom.

The first one-and-a-half miles of the flyover tracks the course of the A4 which is directly beneath it, effectively forming a two-tier road system.

The opening ceremony for the flyover, which was performed by Hollywood actress Jayne Mansfield, took place on 30 September 1959.

In October 2009, actress Imogen Stubbs unveiled a plaque in a ceremony in Chiswick to celebrate the fiftieth anniversary of the opening of the flyover.
