While the bridge itself is not much to look it, it is an important link between the north of the river Thames (Aldwych & the Strand) and the Southbank and Waterloo. Make sure you take time to walk over the bridge - it provides a magnificent photo opportunity - to the west you'll get a lovely shot of the London Eye, Big Ben and the Houses of Parliament; to the east you'll see St Paul's and the city, Canary Wharf and the Shard.
