The actual bridge is quite beautiful and a fascinating piece of early 20th century architecture. It's really cool going underneath one of the arches in Riverside Park and marveling at the meticulous engineering of the massive stone blocks and how tightly they fit together.

The pedestrian walkway is another story unfortunately. Loud, narrow, and covered in graffiti, and the underpasses on the Hartford side are occupied by old homeless encampments which reek of urine and feces. If you're on the East Hartford side I'd recommend turning around and going over the Founders Bridge rather than doing a full loop.
