CENTERVILLE, Pa. — Authorities in western Pennsylvania have reopened a road where hydrochloric acid was spilled in a crash involving a train and a tractor-trailer.

Officials reopened a stretch of Route 88 in Centerville late Tuesday following a crash earlier that day. Authorities say residents who were evacuated have been allowed to return home. Crews have been removing contaminated soil from the site.

The truck was carrying more than 22 tons of hydrochloric acid, which the Environmental Protection Agency says is corrosive to the eyes, skin and mucous membranes and can cause burns if inhaled. Authorities say the truck’s driver was airlifted to a Pittsburgh hospital.

The Federal Railroad Administration says there have been four collisions involving a train at the intersection since 2010.
