VIEW CARDIFF CAMERAS âCardiff, the capital city of Wales, is a vibrant cultural and economic powerhouse positioned at the strategic heart of the South Wales transportation network. Serving as the primary transit hub for those moving between Newport, Swansea, and the England border, Cardiff handles an immense daily volume of commuters and international freight. With the M4 motorway serving as the region's singular high-capacity link, managing the flow of over 122,000 daily vehicles through its mountain tunnels and city arterials is essential for maintaining the nation's accessibility and resident quality of life.
TrafficVision aggregates feeds from Traffic Wales (Traffig Cymru) and local municipal sources, providing a comprehensive view of the United Kingdom camera network. Whether you're navigating the morning rush toward the city centre or heading to a match at the Principality Stadium, our live street cameras help you bypass the most notorious bottlenecks in real-time.
M4 Motorway
The primary artery for South Wales. Monitor traffic through the high-volume Cardiff segments from Junction 32 (Coryton) through to the Newport interchanges.
Brynglas Tunnels
The UK's most critical Welsh chokepoint. Monitor real-time flow through the twin-bore tunnels where the M4 narrows to two lanes. Essential for identifying backups before they reach Cardiff.
A48 (Eastern Avenue)
Cardiff's main inner-city bypass. Keep an eye on the critical link between the M4 and the city centre. Check for local gridlock near the University Hospital of Wales.
A470 (North Road)
The vital northern link to the Valleys. Monitor traffic flow through the major interchanges at Gabalfa and toward the Brecon Beacons.
Welsh Capital Coverage
Extensive visibility across Cardiff, Penarth, Barry, and the primary government districts.
Tunnel Monitoring
Real-time feeds for the M4 Brynglas Tunnels, essential for checking "pinch-point" congestion.
Highway Monitoring
Dedicated feeds for the M4, A48, A470, and major regional A-roads.
24/7 Free Access
No account or subscription required to view any public feed on our map.
Strategic Mobility in South Wales
The traffic landscape in Cardiff is a coordinated effort between Traffic Wales and the Cardiff Council. The region handles some of the highest daily volumes in the UK; the M4 segment near Newport alone is considered one of the top 50 traffic hotspots in all of Europe, with peak usage often exceeding 5,000 vehicles per hour.
While Cardiff residents benefit from a growing cycling network, the reality for many commuters remains a journey that can easily exceed 27 minutes during peak periods. Real-time monitoring is a vital daily tool. Research suggests that live traffic camera feeds can reduce secondary accident rates by up to 30%. By spotting a backup at the Gabalfa interchange early, you can use our route builder to find a faster alternative through local B-roads or the regional rail corridors.

OPEN INTERACTIVE MAP âKey Commute Patterns and Event Impact
Traffic in Cardiff is heavily dictated by the "inbound morning, outbound evening" pattern serving the capital's workforce, further complicated by the massive population surge during international rugby matches and concerts. Peak morning hours (7:30 AM â 9:00 AM) see extreme volume heading toward the city core via the A470 and A48, while the evening rush (4:30 PM â 6:30 PM) brings that volume back toward the residential districts of the Valleys and the Vale of Glamorgan.
The M4 Brynglas Tunnels remains the most monitored chokepoint in Wales. Our grid view allows you to monitor these multiple tunnel portals side-by-side, helping you decide if taking the southern bypass is a better option today. This is especially vital during South Wales' frequent heavy rain and fog events, which can suddenly impact visibility and road traction on the high-speed motorway spans.
Pro Tip: Principality Stadium Event Strategy
During major events in the city centre, roads around the Principality Stadium and Cardiff Arms Park can become completely gridlocked. Check our cameras at the Gabalfa and Culverhouse Cross exits at least two hours before event start times to identify the least congested approach to the city's park-and-ride facilities.
