Severn, << SEHV uhrn, >> River, is one of the United Kingdom’s longest rivers and one of its chief waterways. It rises in central Wales and winds about 200 miles (322 kilometers) through England to the Bristol Channel. Two bridges cross the river at Beachley. Used by motor vehicles, their roadways form part of the main road between England and Wales. A railroad from London to Wales uses a 4-mile (6.4-kilometer) tunnel under the river’s mouth. Canals connect the Severn with the Trent, Thames, and Mersey rivers. Bores, huge waves caused by rising ocean tides, often flood the banks of the Severn Estuary.
