Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: 'The 8 span, 720'-long rivet-connected steel Warren (with verticals) pony truss bridge, built in 1935, is supported on stone piers and abutments with concrete caps. The truss members are rolled sections, and the bottom chords are composed of channel sections. Rolled floorbeams and stringers support the concrete deck. Angle section railings are fixed in front of the railings, and a metal railing with cast posts along the sidewalk. Although a large example, the bridge is not historically or technologically significant because it is a late and standard application of riveted Warren truss bridge technology.'

Keim Street Bridge
Posted December 4, 2010, by Chester Co. Historian Leonard F. Shaner, JR. (Conrail6370 [at] hotmail [dot] com)

This bridge replaced the Wooden Covered bridge that was once across the Schuylkill River at this spot. The bridge is own by the two counties.

This bridge has been condemned. Neither Pottstown nor North Coventry want to pay for it's replacement.
