Forty Foot Pedestrian Bridge / Towamencin Township, Montgomery County, Penn.
The 13-in.-deep haunches on the box beams and
fascia panels can be easily seen with the deck forms
in place. Providing haunches simplified forming, tying
reinforcement, and placing concrete for the cambered
deck. Paint on the deck form outlines the shape of a
cast-in-place concrete planter. Photo: Simone Collins
