    Yeah I've done a bit more research & a second site visit and you're right about the legs not being bedsteads. Sorry, premature conclusion. I thought maybe they extended down into the concrete abutments, since many bedsteads have their legs encased in concrete, but that's clearly not the case.

    The spillway elevation was raised from 187' to 300' in 1963. Prior to this time there was a crossing of the upper lake at the bottom of section 22, so a possible earlier location for this bridge. The earlier, lower level lake did not have a road across the spillway.

    I agree Luke, I don't see anything to suggest the endposts extend down to create truss legs.

    Doubtful, as a bedstead has legs that function as support/substructure, and this appears to be more of a case of vertical endposts.

    I feel like this could technically be reclassified as a bedstead Pennsylvania through truss - perhaps the only on on the site - because the end posts do act like those of a traditional bedstead in this relocated single-span scenario.

    Because of the vertical end posts, this bridge appears to me to have been one span of a multi span bridge when first installed at the original unknown location.

    Why doesn't it say where the bridge was moved from? It wasn't built where it's at.
