New data has revealed Westminster has the most congested road in England, according to a study using government statistics on road delays.
The A5204 in Westminster is the most congested road in England, with an average delay of 456.1 seconds per vehicle per mile.

The top two A roads with the longest average delays per vehicle per mile were both in Westminster, while the third was in Camden.
The second most congested road in Westminster, the A4201, had an average delay of 324.7 seconds per vehicle per mile.
