Bridge Snapshot: T-357
The T-357 bridge in Union, Pennsylvania carries T-357 over N. BR. BUFFALO CREEK. It was built in 1900, making it 126 years old today. It was last reconstructed in 1954, extending its service life. The structure is built primarily of steel and spans 1 section, stretching 16.8 meters (55 feet) end to end. Daily traffic averages 119 vehicles, placing it in the lower-traffic tier of Pennsylvania bridges. It is owned and maintained by County Highway Agency.
The latest FHWA inspection records show a deck rating of 6/9, superstructure at 1/9, substructure at 1/9. The weakest component sits in critical condition. Because at least one major component scores 4 or lower, this bridge falls in FHWA's Poor condition category. That category is not a closure order.
