SHARPSBURG, Pa. — A semi-truck rolled over on a bridge in Allegheny County, shutting down the 62nd Street Bridge for hours.
The crash happened on the Sharpsburg side of the bridge, just before 9:30 p.m. on Monday. The truck was uprighted and removed by 12:40 p.m. Tuesday, and the bridge reopened around 30 minutes later.
Sources tell Channel 11 that a corrosive liquid leaked out of the truck. Allegheny County HAZMAT crews were called to the scene, and the Department of Environmental Protection was notified.
Allegheny County Emergency Services later said the trailer was carrying a mixed load, consisting mostly of lactic acid. The acid is considered hazardous, causing severe skin burns and eye damage.
ACES added that absorbent material and a neutralizing agent were used to contain and control the spill.
Officials asked drivers to seek alternative routes for the morning commute.
While county emergency crews left the scene by 5 a.m., other workers remained, cleaning and removing material from the truck.
