Ravine Road Bridge
Notice how the original railings stop for the end posts.

The 4 section pony Pratt/Howe bridge is made from non-flared I beams (standard width flat flange?), welded together. Gusset plates are used but they are so small that they may have been added at a later date. Top chord is 2 I beams welded to a top plate. Diagonals are single beams, but counters - both sets - are I beams just as heavy as the diagonals; thus this one could be called a Howe. End posts are made from 2 I beams, open but connected with a few small plates. Outriggers may be original and just welded on. Bridge is clearly marked "Warren 1938". Floor beams appear as old as the outriggers. Steel is by Carnegie. Deck is timber under asphalt. Secondary abutment next to bridge implies this one replaced something much older, or was itself moved a dozen feet at some point.
