Westminster Bridge is a road and foot traffic bridge over the River Thames between Westminster on the north side and Lambeth on the south side, in London. The bridge is painted predominantly green, the same colour as the leather seats in the House of Commons which is on the side of the Palace of Westminster nearest the bridge. This is in contrast to Lambeth Bridge which is red, the same colour as the seats in the House of Lords and is on the opposite side of the Houses of Parliament.
