About This Camera
Camera Location & Hazard Overview
A102 traffic reports for South East London almost always come back to this single stretch: the Blackwall Tunnel Southern Approach, where the road funnels into two Victorian-era bores beneath the Thames. Few feeds do more to tell commuters whether the tunnel is flowing or stacked back onto the flyover. Few roads in London carry quite this weight of expectation from a single camera feed, given how many South East London journeys depend on the tunnel staying open.
Traffic Pattern & Congestion Trends
Northbound traffic queues past Sun-in-the-Sands roundabout from around 06:00, often not clearing until mid-morning, while the approach itself can lock solid within minutes of an incident inside either bore. Southbound flow in the evening peak moves faster, since it's dispersing rather than funnelling. Friday evenings are typically the worst of the week, as weekend getaway traffic compounds the usual commuter flow heading north.
Traffic Fines & Camera Enforcement
Continuous yellow-box and bus lane cameras cover the approach, since it operates as a Red Route. Overheight vehicle sensors sit just ahead of the portals, and a lorry striking one triggers an automatic closure with a fast-forming tailback right through this camera's field of view.
Road Closures & Alternative Routes
A full tunnel closure pushes traffic onto the Woolwich Ferry or the size-restricted Rotherhithe Tunnel; neither copes well with Blackwall's volume, so expect both to slow down too. Cutting through Greenwich town centre is actively discouraged by LTN filters and rarely saves time. HGV drivers in particular should check their vehicle height twice before joining this queue, since a rejected lorry can't easily turn round once committed to the approach, and a jackknifed vehicle here can turn a routine delay into a genuine motorway breakdown recovery job.
Driver Safety & Local Tips
If this camera shows solid red right up to the portal, don't join the queue — TfL's tunnel status page updates faster than the traffic clears, and a Woolwich Ferry crossing can beat a stationary 40-minute tunnel queue on a bad day.
ULEZ & Emissions
Greenwich sits inside the expanded Ultra Low Emission Zone, which has run 24/7 since August 2023. Non-compliant petrol cars pre-2006 and diesels pre-2015 pay £12.50 a day on top of any Congestion Charge liability. Check a specific plate at tfl.gov.uk/ulez before travelling into the borough.
Parking near A102 Blackwall Tunnel Sth Appr, East Ham and Barking
There's no realistic on-street stopping directly on the Blackwall Tunnel Southern Approach itself, given the Red Route restrictions, so drivers heading this way should plan to park before joining the A102. The nearest options are the Greenwich Peninsula car parks near the O2, or the residential CPZ streets around Kidbrooke and Sun-in-the-Sands, which run Monday to Saturday during the day under Royal Borough of Greenwich rules. Single yellow lines nearby restrict loading and waiting during the same controlled hours; double yellows are no-stop at any time. Locals heading into Greenwich itself often park a street or two back from Trafalgar Road and walk in, since resident bays fill fast. Check exact CPZ hours on the council's signs, and use royalgreenwich.gov.uk/parking for permits, RingGo codes and PCN appeals.
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.
