About This Camera
Camera Location & Hazard Overview
Named after the artist William Hogarth, whose former house sits nearby, the Hogarth Roundabout is where the A4 meets the A316 close to Chiswick, and this camera covers one of West London's most congested junctions, notorious for long queues at almost any time of day. Few junctions on the entire network carry quite the same reputation among regular London drivers as this one does.
Traffic Pattern & Congestion Trends
This roundabout rarely sees genuinely free-flowing traffic during daylight hours on weekdays, with queues common well outside the traditional rush-hour windows due to the sheer volume of traffic converging here from multiple directions simultaneously, and Hogarth Roundabout's confusing lane markings make it one of West London's more reliable generators of a car accident compensation claim. Even a Sunday afternoon can bring surprisingly heavy traffic through this junction, particularly during the summer months when tourist traffic adds further pressure to an already busy roundabout.
Traffic Fines & Camera Enforcement
Both average speed cameras and yellow box enforcement operate at this junction, reflecting its long-standing reputation as one of the most congestion-prone points on the entire A4 corridor, with enforcement designed specifically to stop the roundabout seizing up entirely during its busiest hours. Hogarth Roundabout's confusing lane markings have long made it one of West London's more reliable generators of a car accident compensation claim.
Road Closures & Alternative Routes
There's no simple diversion around Hogarth Roundabout given its position at the convergence of major routes, though some local drivers use Burlington Lane to bypass the worst of the queuing for journeys not needing the A316 directly, accepting a longer but often more reliable route instead of sitting in the queue waiting for the roundabout to clear, particularly during the worst of the morning rush, and a driver rear-ended while queuing here would have straightforward grounds for a personal injury claim given how predictable this congestion is.
Driver Safety & Local Tips
Hogarth's House, the artist's former home, sits right beside this roundabout and is open to visitors — a pleasant contrast to the near-constant traffic that has made this junction one of London's most infamous, and well worth a visit if you're passing through on foot rather than by car.
ULEZ & Emissions
The London Borough of Hounslow operates entirely within the expanded Ultra Low Emission Zone (ULEZ), active 24/7. Non-compliant vehicles face a £12.50 daily charge. No Congestion Charge applies here, but be aware of Heathrow drop-off charges nearby. Check your vehicle compliance at tfl.gov.uk.
Parking near A4 Hogarth Roundabout, Putney and Mortlake
Hogarth Roundabout itself has no parking given its notorious congestion and scale, and nor do the immediately surrounding stretches of the A4 and A316 — this genuinely isn't a spot to look for kerbside space at any time of day. The surrounding Chiswick residential streets carry a tightly controlled CPZ, with permit bays required during the day and limited visitor pay-and-display. Hogarth's House itself has no dedicated visitor car park, so use the nearby Chiswick High Road public car parks if you're visiting on foot. Hounslow's CPZ map and permit information sit at hounslow.gov.uk/parking for the surrounding Chiswick streets around Hogarth's House.
If on-street parking is hard to find, apps like JustPark and YourParkingSpace let you pre-book a private driveway or car park nearby — typically from around £2–£6 per hour or £10–£25 per day depending on how central the location is.
