Pennsylvania Department of Transportation (PennDOT) has posted restrictions on two bridges in Erie County after a routine inspection uncovered deterioration to the bridges, the department announced Tuesday.

They affect the Station Rd. (Route 430) bridge in Harborcreek Township and the Turnpike Rd. bridge in Wayne Township.

Both bridges are now limited to one truck at a time.

The restrictions will reduce strain on the bridges and preserve safety until they can be repaired or replaced.

Station Rd. over Four Mile Creek is a 50-foot, concrete bridge. It was built in 1941 and is classified as being in fair condition. Approximately 5,500 vehicles use the bridge daily.

Turnpike Road over Baskin Run is a 55-foot, steel, I-beam bridge that was built in 1959. It is considered to be in fair condition. About 300 vehicles use the bridge each day.
