Live Traffic Camera—A4 Great W Rd/Syon Ln

The A4 Great W Rd/Syon Ln area follows typical London traffic patterns — weekday rush hours (07:30–09:30 and 16:30–19:00) are consistently the busiest periods, with school term-time adding pressure around 08:15–09:00 and 15:00–16:00 on school days. Midweek tends to be heavier than Mondays or Fridays, when more people work from home. Saturday lunch and early afternoon can also be surprisingly busy for shopping and leisure trips. The live JamCam above, updated every five minutes by TfL, is the most reliable way to check actual conditions right now.

This location is outside the Congestion Charge Zone, so no CC charge applies. However, like all roads in Greater London, this location falls inside the ULEZ boundary, meaning ULEZ applies here 24 hours a day. Most petrol cars from 2006 onwards and diesel cars from 2015 onwards are compliant and pay nothing. Older vehicles face a daily ULEZ charge of £12.50. Check TfL's free vehicle checker at tfl.gov.uk to find out if your car or van is affected.

Yes — TfL JamCam cameras operate and transmit images 24 hours a day, 7 days a week. However, at night or in low-light conditions, image quality may be reduced. The camera image refreshes every five minutes at all hours. If the feed shows an error, the camera may be temporarily offline for maintenance. TfL's network has very high uptime — try refreshing after a few minutes if the image isn't loading.
