Carlisle/York, PA – The Slate Hill Road Bridge was closed today, Thursday, Feb. 25, for the safety of our residents. The bridge, which carries Slate Hill Road over the Yellow Breeches Creek in Lower Allen and Fairview townships, is jointly owned by York and Cumberland counties.
During a scheduled safety inspection, in accordance with the National Bridge Inspection Standards (NBIS) program, engineers determined that based on the poor condition of several components of the bridge, and evidence that it is being used by overweight vehicles, the bridge is no longer safe for traffic.
Based on traffic counts completed in 2019, the bridge carries approximately 1,600 vehicles per day, and has a 3-ton weight limit. The Slate Hill Road Bridge, a four-span Earth Filled Stone Masonry Arch Bridge built in 1900, is eligible for the National Register of Historic Places.
The bridge has been slated to undergo extensive renovations and restoration scheduled to begin in May. For the safety of our residents, and the preservation of the bridge, it will remain closed until late December, the expected completion of the project.
