PROJECT DESCRIPTION
The Second Severn Crossing provides essential additional traffic capacity across the Severn River and estuary between England and Wales approximately 3 miles (5 km) down river of the original bridge. The Second Severn Crossing Bridge cost $613 million (£330 million) to construct between 1992 and 1996. It is a cable-stayed steel girder and truss bridge with a center span of 1,482 feet (456 meters), a total bridge length of 3,081 feet (948 meters), and a height of 120 feet (37 meters) above the river, as shown in Exhibit 3.9. The first Severn Crossing Bridge was built in 1966 as a standard suspension bridge, as shown in Exhibit 3.10 on the next page.

There are also two viaducts on either side of the cable-stayed suspension bridge of about 1.3 miles (about 2,100 meters) each. The total length of the Second Severn Crossing Bridge and its two approach viaducts at 3.2 miles ( 5.1 km), carrying six lanes of traffic over the Severn River.
When combined, the two bridges over the Severn River carry 66,000 vehicles over the Severn River each day, amounting to over 12 million vehicles on an annual basis. Unlike the original Severn Crossing Bridge, there are no pedestrian/cycle paths on the Second Severn Crossing Bridge. Exhibit 3.11 shows in detail the location of the two Severn Crossing bridges.
