3rd Street Bridge
Posted March 4, 2012, by Matt Lohry

Luke,

This is a sub-divided Warren through truss, which can be easily mistaken for a Baltimore; they look very similar. The way to tell the difference is to imagine the bridge without the smaller half-panel diagonals. In this case, without those smaller diagonals, you would have a standard Warren configuration. If it were a Baltimore, you would have a Pratt configuration rather than a Warren. Hope this helps!

Is it me or does this look more like a Baltimore?
