About This Camera
Camera Location & Hazard Overview
Henlys Roundabout, where the A4 Bath Road meets several access roads converging from different directions, is a well-known interchange for drivers approaching Heathrow's northern perimeter from the Hounslow side, and this camera keeps watch over what's become a common source of localised congestion given the sheer number of routes feeding into this single point throughout the working day and beyond.
Traffic Pattern & Congestion Trends
Traffic builds through the morning as airport-bound commuters and passenger traffic converge on the roundabout from multiple directions at once, with a similar but reversed pattern developing during the evening as traffic disperses back towards Hounslow once the working day winds down, typically easing off by early evening on most weekdays outside of school holidays and major public events nearby — and this roundabout's multiple confusing exits are a recognised local hotspot for a car accident solicitors' caseload.
Traffic Fines & Camera Enforcement
The Bath Road approaches here are covered continuously by average speed cameras at 40mph, with ULEZ ANPR monitoring active given the roundabout's location well within the expanded zone that now covers the entirety of Hounslow borough, meaning both speed and emissions compliance are checked simultaneously here. This roundabout's multiple confusing exits have long made it a recognised local source of the kind of collision behind a road traffic accident claim.
Road Closures & Alternative Routes
The A3006 and surrounding Heathrow access roads provide alternative approaches to the airport perimeter if Henlys Roundabout is severely congested, though local knowledge genuinely helps here given how complex the surrounding road layout can be for unfamiliar drivers attempting a shortcut through this area for the very first time without any prior familiarity with the junction layout or the direction each exit actually leads towards.
Driver Safety & Local Tips
This roundabout's multiple exits can confuse drivers unfamiliar with the area — decide on your exit well in advance, since late lane changes here are a frequent cause of minor incidents among those navigating it for the first time without local knowledge.
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 Bath Rd/Henlys Rabout, West London
Henlys Roundabout itself has no parking given its role as a major airport-facing interchange, but the surrounding Hounslow residential streets nearby carry CPZ restrictions typical of areas this close to Heathrow — expect permit-only bays during the day with visitor pay-and-display more limited. Always check individual street signs rather than assuming free parking near an airport perimeter road. There's no major public car park directly here; Heathrow's official car parks are the better choice if you're flying rather than attempting residential streets nearby. Single yellow lines around the roundabout approaches restrict stopping at all times. Hounslow's parking pages sit at hounslow.gov.uk/parking for the surrounding residential zones.
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.
