Westminster Bridge crosses the River Thames close to the London Eye and the Houses of Parliament. Built between 1738 and 1750, it was the second bridge built to cross the Thames. The current bridge, however, was designed by Thomas Page and opened in 1862. With a total length of 76.2 m spanning the seven arches and a width of 26 m, Westminster Bridge is a metallic bridge with Gothic details designed by Charles Barry (the architect who designed the Houses of Parliament). The bridge is well-known for its special green colour.
