Gilbert Bridge

The Gilbert Bridge is a steel bridge that spans the Yellow Breeches Creek, connecting Monaghan Township in York County with Upper Allen Township in Cumberland County. It has a width of about 18 feet and was designed to carry local traffic between these two communities.

The Wrought Iron Bridge Company constructed this bridge in 1899 using a Pratt truss design, which was typical for Pennsylvania infrastructure of that era. It was later listed on the National Register of Historic Places in 1989, reflecting its technical and historical importance.

The National Register of Historic Places listed the Gilbert Bridge in May 1989, recognizing its architectural merit and contribution to American bridge engineering.

Access to this bridge is from Bishop Road and Gilbert Road, making it easy to locate from local streets. It is advisable to drive slowly and watch for the narrow curves as you approach the span.

The bridge uses a Pratt truss design where diagonal members work in tension to distribute loads effectively across the span. This system was popular in late 19th-century bridge engineering because it saved weight while still carrying heavy loads.
