Police and emergency crews are responding to reports of a man jumping from the Route 28 bridge over Buffalo Creek. It’s unclear whether the man survived the fall.

Calls from witnesses were first reported just after 1:30 p.m. Thursday.

State and Buffalo Township police were on the bridge, but traffic was moving normally on Route 28.

Other crews were accessing the scene via the Butler-Freeport Community Trail at the Monroe Road trailhead. The trail is shut down at that point.

Buffalo Township VFD Chief Matt Cypher said the zone would serve as the main staging ground for emergency crews.

Crews from Buffalo Township, Saxonburg and Harrison were visible at the scene.

The trail is the only access to the deep gorge the bridge spans. There are no roads in the immediate vicinity.

An empty SUV sat parked along the highway on the bridge.

A deputy coroner for Butler County said, to her knowledge, the coroner had not been called to the scene.
