Severn Bridge Cameras: Real-Time M48 and Prince of Wales Bridge Monitoring
Stay ahead of the England to Wales commute with live Severn crossing live cam coverage from National Highways. From the original M48 Severn Bridge to the M4 Prince of Wales Bridge, get instant visibility into wind closures, HGV diversions, and queues at the estuary 24/7.
VIEW SEVERN CAMERAS →The Severn crossings are the only fixed road links between South Wales and South West England, carrying the M4 and M48 over a 14-mile estuary stretch that funnels every cross-border lorry, commuter, and holidaymaker through two bridges. The older M48 Severn Bridge opened in 1966, while the longer Prince of Wales Bridge on the M4 opened on 5 June 1996 to add capacity and a more direct route into Newport and Cardiff. Together they form the busiest segment of the United Kingdom motorway network west of London, with the M48 alone carrying around 32,000 vehicles per day in 2024.
TrafficVision.Live aggregates feeds from National Highways and Traffic Wales, giving you a single view across both spans, the approaches at Aust and Magor, and the connecting M4, M48, and M49 corridors. Whether you are routing a 7.5-tonne lorry that can no longer use the M48, or checking whether wind has shut the older span entirely, our live street cameras let you decide before you commit to a lane.
M48 Severn Bridge (Aust to Chepstow)
The original 1966 suspension bridge. Monitor the Aust approach, the main span, and the Beachley viaduct. Closes to all traffic when wind gusts exceed 46 mph because it lacks the wind barriers of the newer crossing.
M4 Prince of Wales Bridge (Severn Beach to Magor)
The 1996 cable-stayed crossing, 5,128 metres end to end with a 456-metre main span. Carries all HGVs over 7.5 tonnes since the May 2025 M48 weight restriction. Expect heavier freight volume than before.
M49 Severn Beach Link
The short connector between the M4 and M5 south of the Prince of Wales Bridge. The key relief route for traffic heading toward Bristol and the South West when the M4 backs up at Magor.
A48 Chepstow Alternative
The non-motorway route via Chepstow and the old Severn Bridge approaches. Useful when both motorways are queueing, but expect slow going through the town centre.
Twin Crossing Coverage
Dedicated visibility for the M48 suspension bridge, the M4 cable-stayed span, and both sets of approach viaducts.
HGV Diversion Monitoring
Real-time views of the M4 corridor now carrying every lorry over 7.5t after the M48 weight ban.
Wind Closure Awareness
Spot the moment the M48 shuts in high winds so you can reroute via the Prince of Wales Bridge before queues form.

Strategic Mobility at the Severn Estuary
The traffic landscape across the Severn is now reshaped by two events: the abolition of tolls on 17 December 2018, and the 7.5-tonne weight restriction introduced on the M48 on 27 May 2025. The toll change has driven a 34 percent rise in traffic across both crossings since 2018, and the weight ban now pushes every lorry over 7.5 tonnes onto the M4 Prince of Wales Bridge, a 14-mile diversion for HGVs that would previously have used the M48.
Crossing delays during peak hours can routinely exceed 20 minutes between the Aust services and the Magor interchange. Research suggests that live traffic camera feeds can reduce secondary accident rates by up to 30 percent. By spotting a closure or HGV queue early, you can use our route builder to swap onto the alternative bridge or take the A48 through Chepstow before you commit.
Plan Your Severn Crossing
Avoid the morning M4 queue at Magor or a sudden M48 wind closure. Use our interactive map to see every camera along your route from Bristol to Newport and beyond.
OPEN INTERACTIVE MAP →Wind, Weather, and Closure Patterns
The Severn estuary funnels weather across the bridges in a way that catches drivers off guard. National Highways closes the M48 Severn Bridge when gusts exceed 40 knots (46 mph) because the older span lacks the wind barriers retrofitted to the M4 crossing. If gusts exceed 70 knots (80 mph), both bridges shut. Winter and early spring are the highest-risk windows, and shutdowns can happen with under an hour of notice.
Peak commuter flow runs east to west into Wales during morning hours (7:30 AM to 9:00 AM) and reverses in the evening (4:00 PM to 7:00 PM). Holiday traffic toward Cardiff and the South Wales coast pushes summer Friday and Sunday volumes well above weekday peaks. Our grid view puts the M48, Prince of Wales Bridge, and M49 link cameras side by side so you can choose the right span before the queue starts.
Pro Tip: Watch the HGV Diversion
Since the M48 closed to lorries over 7.5 tonnes in May 2025, an estimated 3,270 HGVs per day have been pushed onto the M4 Prince of Wales Bridge. If you are driving a car and see the M4 backing up at Magor, the M48 is often the faster choice. Check both spans on our cameras before you split off.

What is the difference between the Severn Bridge and the Prince of Wales Bridge?
They are two separate crossings. The M48 Severn Bridge opened in 1966 and is the original suspension bridge between Aust and Chepstow. The M4 Prince of Wales Bridge, originally called the Second Severn Crossing, opened on 5 June 1996 and was renamed in 2018. It is a cable-stayed bridge with a total length of 5,128 metres.
Are there still tolls on the Severn Bridges?
No. Tolls were permanently abolished on 17 December 2018 on both the M48 Severn Bridge and the M4 Prince of Wales Bridge. Crossing in either direction is now free.
Why are HGVs banned from the M48 Severn Bridge?
National Highways introduced a 7.5-tonne weight restriction on the M48 on 27 May 2025 after routine surveys found deterioration in the main bridge cables. All HGVs over 7.5 tonnes must now use the M4 Prince of Wales Bridge. The restriction is expected to last 12 to 18 months while a new traffic management system is installed.
When does the M48 Severn Bridge close for wind?
The M48 closes to all traffic when wind gusts exceed 40 knots (about 46 mph) because it lacks the wind barriers fitted to the newer M4 crossing. If gusts exceed 70 knots (about 80 mph), both bridges close.
Is there a cost to use the TrafficVision.Live platform?
No. TrafficVision.Live is a 100 percent free service providing access to official public traffic feeds across the UK and over 130 countries worldwide.
