M25 Traffic on Mondays
Monday mornings on the M25 bring the commute around London back all at once: drivers heading for Heathrow, the business parks of the Thames Valley and Surrey, and the industrial estates of Essex and Kent.
This page shows how the latest Monday went, clockwise and anticlockwise, hour by hour. The cards pick out the slowest hour and the slowest stretch, so you can see which part of the loop was worst.
