PROJECT DESCRIPTION
A bow-string Pratt Truss girder bridge formed by mechanically curving the top chord into an arch shape along a parabolic curve. It has vertical members at every panel point which shrinks the floor beams and minimizes or eliminates stringer beams. The Seneca style has an elegant look that is aesthetically pleasing and is typically used to enhance commercial areas, driveways or entry points.
