Prince of Wales Bridge – A Modern Engineering Marvel
The Prince of Wales Bridge, formerly known as the Second Severn Crossing, stands as a vital link between England and Wales, carrying the M4 motorway over the River Severn. Opened in 1996, this impressive structure was designed to alleviate traffic congestion from the original Severn Bridge and enhance connectivity between the two nations. Spanning over 5 kilometers, the bridge showcases remarkable engineering and continues to play a crucial role in the UK’s transportation network.
Introduction
The Prince of Wales Bridge is a significant infrastructure project that connects South West England to South East Wales. It serves as a primary route for commuters, travelers, and freight transport, facilitating economic and social interactions between the regions. The bridge’s construction addressed the limitations of the original Severn Bridge, providing a more direct and efficient crossing for the M4 motorway.
History and Background
Why Was the Prince of Wales Bridge Constructed?
By the late 20th century, the original Severn Bridge, opened in 1966, was struggling to accommodate the increasing volume of traffic between England and Wales. Frequent closures due to high winds and maintenance issues further exacerbated congestion problems. To address these challenges, the UK government initiated plans for a second crossing over the River Severn. Construction of the new bridge began in 1992, and it was officially opened by Prince Charles on 5 June 1996. In 2018, the bridge was renamed the Prince of Wales Bridge in his honor.
Design and Construction
What Are the Key Design Features of the Bridge?
The Prince of Wales Bridge is a cable-stayed structure, a design chosen for its ability to cover long spans and its aesthetic appeal. The bridge’s total length is approximately 5,128 meters (16,824 feet), with a main span of 456 meters (1,496 feet) between its towering pylons, each standing 137 meters (449 feet) tall. The deck is supported by 240 stay cables, providing both strength and flexibility to withstand the estuary’s challenging environmental conditions. The bridge offers a navigational clearance of 37 meters (121 feet), allowing vessels to pass beneath it safely.
Construction Timeline
Construction of the Prince of Wales Bridge commenced in 1992 and spanned four years, culminating in its opening in June 1996. The project involved significant engineering feats, including the installation of massive precast concrete foundations to support the bridge’s piers in the estuary’s tidal environment. The use of advanced construction techniques and materials ensured the bridge’s durability and capacity to handle substantial traffic loads.

These specifications highlight the bridge’s capacity to accommodate high traffic volumes and its ability to endure the estuarial environment’s challenges.
Traffic and Usage
Since its inauguration, the Prince of Wales Bridge has been a critical artery for vehicular movement between England and Wales. It carries the M4 motorway, facilitating six lanes of traffic and significantly reducing congestion that once plagued the original Severn Bridge. The bridge’s design includes features to mitigate disruptions caused by high winds, ensuring more consistent and reliable travel conditions for motorists.
Tolls and Ownership
When Were Tolls Abolished on the Bridge?
Initially, crossing the Prince of Wales Bridge required the payment of tolls, a system implemented to recoup construction and maintenance costs. These tolls were collected until December 2018, when they were abolished, making crossings free for all vehicles. The removal of tolls was welcomed by commuters and businesses alike, as it reduced travel costs and was anticipated to boost economic activity in the region.
Maintenance and Recent Developments
What Maintenance Work Has Been Undertaken Recently?
In 2024, the Prince of Wales Bridge underwent its first major renovation since opening nearly three decades earlier. The maintenance work included resurfacing and concrete repairs aimed at extending the bridge’s lifespan and ensuring safety for its users. Traffic management measures, such as lane closures and diversions, were implemented during the maintenance period to facilitate the work while minimizing disruption to motorists. The renovations were expected to be completed by the end of autumn 2024.

Why was the bridge renamed the Prince of Wales Bridge?
In July 2018, the bridge was renamed in honor of Prince Charles, the Prince of Wales, to mark his 70th birthday and to recognize his longstanding service to Wales.
How long is the Prince of Wales Bridge?
The bridge has a total length of approximately 5,128 meters (16,824 feet), making it a significant feat of engineering.
Is there a toll to cross the Prince of Wales Bridge?
No, tolls for crossing the Prince of Wales Bridge were abolished in December 2018. Since then, it has been free to cross in both directions.
Can pedestrians or cyclists use the Prince of Wales Bridge?
No, the Prince of Wales Bridge is part of the M4 motorway and is not accessible to pedestrians or cyclists. However, the nearby M48 Severn Bridge has provisions for both pedestrians and cyclists.
What type of bridge is the Prince of Wales Bridge?
It is a cable-stayed bridge, characterized by its cables directly connected to towers, which support the bridge deck. This design allows for longer spans and provides greater rigidity compared to traditional suspension bridges.
Why was the Prince of Wales Bridge built?
The bridge was constructed to address increasing traffic volumes and congestion on the original Severn Bridge, which opened in 1966. By providing an additional crossing, it improved traffic flow and connectivity between England and Wales.
Are there any restrictions on the bridge during high winds?
Yes, during periods of high winds, traffic restrictions may be implemented for safety reasons. In extreme cases, the bridge may be closed to all traffic until conditions improve.
What body of water does the Prince of Wales Bridge cross?
The bridge spans the River Severn, which is the longest river in Great Britain, flowing through both Wales and England.
Is the Prince of Wales Bridge the only crossing over the River Severn?
No, there are multiple crossings over the River Severn, including the original Severn Bridge (M48) and the Severn Tunnel for rail transport. The Prince of Wales Bridge is one of the primary motorway crossings.
