Lambeth Bridge

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.

The most conspicuous colour in the bridge's paint scheme is red, the same colour as the leather benches in the House of Lords, which is at the southern end of the Palace of Westminster nearest the bridge. This is in contrast to Westminster Bridge, which is predominantly green, the same colour as the benches in the House of Commons at the northern end of the Houses of Parliament.
