    Charles River Bridge
    Posted August 21, 2013, by Nathan Holth (form3 [at] historicbridges [dot] org)

    This bridge has an unusual history. I updated the page so hopefully it reduces the confusion. It was originally a 1910 single leaf bascule, replaced in 1962 with a double leaf bascule (one of the smallest double leaf bascules I have ever seen) and again demolished and replaced in 2010. As such, the bridge today is modern and has no historic significance.
