Project Description:

The project consisted of Phase I and Phase II Design for three bridge replacements including approach work. Phase I consisted of preparing a Project Report for each structure. The Project Report included a traffic analysis, hydraulic report and bridge condition report. Phase II consisted of complete design and details for a TS&L Plan and Final Plans. The two bridges on US 51 in Fayette County were old reinforced concrete structures and were replaced with prestressed I-beams and cast-in-place concrete deck and all new substructure units. The bridge in Effingham County used steel stringers supporting a concrete deck. The rehabilitation consisted of replacing the entire deck and repairing the existing steel beams and pile bents. Steel bearing shoes were replaced with elastomeric bearing assemblies. All three projects used stage construction to maintain traffic. The Illinois Department of Transportation provided the geotechnical investigation and coordination with environmental agencies.
