Mathematical/Wooden/Queens Bridge?

Anyone who knows me would possibly guess this would be my blip from a day trip to Cambridge!
 
Stories abound about the bridge -  better explained than I could in this Wikipedia article.

Photographed from a punt on the Cam - our guide, Will, was very informative.  Local to Cambridge but a graduate of Bristol.

In the extra, a different type of architectural/structural lines and shapes image.
 
Thanks to everyone who has visited my journal over the past few days, I'll get round to responding once we are back home later this week.

It's too hot to worry about apostrophes, and, if there should be one, where should it go :-)
