Harsco Corp. secured an extended role in its ongoing support of the Metropolitan Transit Authority of Harris County (Houston Metro) light rail project to refurbish the historic Main Street Bridge in Houston.

The work is part of a major expansion of the light rail line from Houston’s city center, adding nearly 30 miles of track to the existing Main Street line.

The complex bridge project has a number of special requirements, including construction of a supporting superstructure over an active waterway, limited storage for equipment, and stringent requirements to maintain the bridge’s historic visual appeal.

Harsco’s turnkey support solution includes a combination of heavy-duty GASS shoring towers and Roll Shore castellated beams, engineered to provide support to the 400 foot-long bridge as well as providing safe worker access throughout the refurbishment.
