The River Thames, known alternatively in parts as the Isis, is a river that flows through southern England including London. At 215 miles (346 km), it is the longest river entirely in England.
Lambeth Bridge is a road traffic and footbridge crossing the River Thames in an east-west direction in central London. The river flows north at the crossing point. Downstream, the next bridge is Westminster Bridge; upstream, the next bridge is Vauxhall Bridge.
