Gedney Lake Bridge
Posted September 14, 2011, by Tony Dillon (spansaver [at] hotmail [dot] com)

I highly doubt that this span was built "unbalanced" like this.

It was likely shortened by those 2 panels being removed, possibly due to some sort of damaged incurred on that end.

Definitely has a unique look now.
