Pearl Street Bridge Replacement

Johnson, Vermont

Design and construction phase services to replace a 159-ft bridge carrying Pearl Street over the Gihon River. Both the railings and deck were heavily deteriorated. The existing concrete bridge railing, considered a historic resource by the State Historic Preservation Office (SHPO), had deteriorated to the point where replacement was the only option. The bridge was the only major access to the north area of the Village including Johnson State College, the municipal offices, and the elementary school. A detour and a temporary bridge were provided during construction.

Project components included superstructure replacement using 150-ft continuous horizontally curved steel beams with a composite concrete deck, a SHPO-approved Texas Classic bridge rail, and new sidewalks on both sides of the bridge. Approach work included roadway realignment, sidewalk and curb, new sub base and pavement, and driveway improvements. Professional services include:

Survey and deed research
Permitting/NEPA documentation
Investigation of viable superstructure and alignment alternatives
Right-of-way plans
Utility relocations
Traffic maintenance via a temporary bridge during construction
