As you exit Holloway Road tube station in the evenings you will see that a lovely green and blue light effect has been installed under the railway bridge to the left. A similar effect has been created in Finsbury Park under the bridge at the bottom end of Stroud Green Road.
Viewed from the 'right' angle or against a deep blue sky even the rustiest old bridge can look beautiful. All of the above images, and many more in a similar vein, can be found on Flickr.
