Trexler Game Preserve Pedestrian Bridge
Schnecksville, PA

A multiple span bridge in a park setting. The bridge links a picnic area to a nature trail. Each span is 90’ with an existing concrete abutment on an island in the middle of Jordon Creek. This project utilized exposed glue-laminated wood construction that was analyzed to provide the most economical amount of wood to create the spans. We also utilized the remaining concrete abutments on the south end and the center island support, left from a previous bridge washed away during a 1972 flood, to serve as foundations for the structure. The north abutment was missing and required reconstruction.The use of existing abutments minimalized the environmental impact on the stream and required alterations for the new stairs and wing walls.
