Second Severn Crossing, the most southerly bridge over the River Severn. The central span of this crossing is supported by a cable-stayed system (centre right), the weight being carried by anchored cables. Approaching the central span on either side are viaducts supported by concrete pillars. High fences, or baffles, (green band) are present on each side to deflect the wind. This bridge was built between 1992 and 1996 to relieve the congestion on the original Severn bridge, which carries traffic between England and Wales.
