Severn

Severn sĕv´ərn , Lat. Sabrina, one of the principal rivers of Great Britain, c.200 mi (320 km) long, rising on Plinlimmon Mt., W Wales, and flowing NE and E to Shrewsbury, W England, and from there SE, S, and SW—through an estuary—to the Bristol Channel. Worcester , Gloucester , and many smaller towns are on its banks. The tributaries include the Teme, Avon, and Stour. It is connected by canal with the Thames , Mersey, Trent, and other rivers. A railroad tunnel (opened 1886) more than 4 mi (6.4 km) long passes under the estuary. The Severn Road Bridge (opened 1966) is one of the world's longest (3,240 ft/988 m) suspension bridges. The river is an important transportation route. Because of the conformation of the estuary, a tidal bore occurs up to Gloucester.
