About This Camera
Camera Location & Hazard Overview
Western Avenue crosses clean over Greenford Road at this flyover, a significant interchange serving traffic moving between the A40 corridor and Greenford, Southall and Northolt. Lorries serving the industrial units around Greenford add a steady undercurrent of heavy traffic that's easy to miss from the flyover deck itself. Even small changes in traffic here tend to ripple outward to neighbouring junctions.
Traffic Pattern & Congestion Trends
The flyover itself generally flows well, but the slip roads connecting to Greenford Road below back up during peak hours as local traffic merges with the dual carriageway flow, particularly in the evening when Greenford Road traffic is heaviest. Friday afternoons see an earlier build-up here than most weekdays, as weekend delivery schedules overlap with the standard commuter flow. Conditions can shift quickly here, so a clear camera feed is only ever a snapshot rather than a guarantee, and a lorry misjudging the flyover merge is an occasional but genuine cause of a car crash claim on this stretch.
Traffic Fines & Camera Enforcement
Ongoing average speed monitoring covers this stretch, cover the flyover and its approaches, with ANPR at the slip road merges. The volume of traffic changing between the A40 and Greenford Road here makes this a closely monitored point on the corridor.
Road Closures & Alternative Routes
Greenford Road itself remains the main alternative for local journeys not needing the A40 directly, though it's typically slower than the flyover during off-peak hours. Regular Greenford commuters generally learn to use the flyover slip roads early in the peak, before the evening rush properly sets in below on Greenford Road. Local drivers generally have a preferred back-up route memorised for exactly this kind of situation.
Driver Safety & Local Tips
If you're heading for Greenford or Southall rather than staying on the A40, use the flyover slip roads early — they can back up quickly once the evening peak properly sets in.
ULEZ & Emissions
Ealing has sat inside the expanded Ultra Low Emission Zone since it went London-wide in August 2023, meaning non-compliant vehicles pay £12.50 a day anywhere in the borough, including the whole of the A40 and Uxbridge Road corridors. Check compliance for your specific vehicle at tfl.gov.uk/ulez before travelling.
Parking near A40/Greenford Flyover, West London
Greenford Flyover itself has no parking, but Greenford town centre nearby offers the Greenford Broadway car park along with pay-and-display bays on the surrounding high street, both useful if you're shopping or catching a train from Greenford station. The Ealing Council CPZ covers residential streets near the flyover, typically Monday to Saturday daytime. Single yellow lines restrict stopping only during controlled hours. Weekend parking is generally easier in Greenford than on a weekday when commuter traffic competes for the same limited station-adjacent spaces.
