Caught Our Eyes: Tower Bridges in Boston, Massachusetts

This image, found while browsing for bridges in the Prints & Photographs Online Catalog, lured a colleague in for a closer look.  I was glancing over her shoulder, and the photograph drew me in and stirred my curiosity, too.

We were struck by the clarity and beautiful geometry of the image, one of the recently rescanned glass negatives from the Detroit Publishing Company Collection.  We also wondered: What’s happening here? How did the bridges work?

Yes, we’re in a library—we could look it up.  But do any of you bridge specialists out there want to shed some light?
