There's something intriguing about bridges -- is it the tantalizing possibilities they offer? What's on the other side? In this photo London's Millennium Bridge is seen from below, set against the backdrop of a bold sky.

The bridge is a steel suspension pedestrian footbridge for crossing the River Thames, which opened in 2000. Its modern design is in stark contrast to the traditional buildings flanking the river.

In this image I juxtaposed the gleeming hard lines of steel with soft white clouds and blue sky.
