Motorway crossings over the River Severn Prince of Wales Bridge (M4 motorway) Severn Bridge (M48 motorway) Queenhill Viaduct (M50 motorway) This is a list of crossings of the River Severn in Great Britain (including bridges, tunnels, ferries and fords), in order from source to mouth. The Severn has historically been a very important and busy river, and has been bridged throughout history. The ...
By the time it was taken into public ownership, the bridge was in very poor condition. In 1891 a weight limit of 5 tons was introduced, and in 1897 a 10 mph (16 km/h) speed limit was imposed. With its narrowness and weight restrictions, by this point it was effectively a footbridge. [9]
If no bridge is located on the route, the worst section of road governs the route's classification. Vehicles having higher load classifications than a particular route are sometimes able to use that route if a recon overlay or a special recon [ clarification needed ] shows that a change in traffic control , such as making a bridge a single-flow ...
In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

The bridge has been widened several times (the first in 1799 and recorded works in 1808, 1830 and 1852), but is undersized for modern traffic; in several places it is scarcely two lanes and cars are unable to pass at several points. [1] Though there is a weight limit of 7.5 tonnes, the walls of the bridge often take damage from traffic.
The original wooden bridge was built in the Middle Ages; there is a clear reference to it in the fourteenth century. Earlier references to a bridge at Monmouth may refer either to a bridge over the Wye or to the fortified bridge over the Monnow, [1] although local historian Keith Kissack wrote that the bridge was known to exist in 1282 when it formed a boundary with the Forest of Dean.

The A48 is a trunk road in Great Britain running from the A40 at Highnam, 3 miles (4.8 km) west of Gloucester, England, to the A40 at Carmarthen, Wales.Before the Severn Bridge opened on 8 September 1966, it was a major route between England and South Wales.
The canal company funded a replacement wooden road bridge served by a toll-house situated at the northern end. There was a weight limit and after World War 2 only single-decker buses were allowed across; if they were carrying too many passengers some had to get out and walk, regardless of the weather, to reduce axle-weight.
