The project consisted of replacing the structurally deficient Conneaut Viaduct which carries U.S. 20 over Conneaut Creek and the active Bessemer and Lake Erie railroad tracks. The project also improved geometrics of the western approach area by eliminating an abrupt horizontal deflection.

The new structure is a two-lane, eight span, continuous, prestressed concrete I-beam bridge, with a composite reinforced concrete deck supported on a reinforced concrete substructure on new alignment adjacent to and immediately south of the existing structure. It also has cap and column type piers (open design) and an open style concrete railing, similar in appearance to the existing. Ornamental light fixtures are installed on the new bridge similar to the lighting fixtures currently in use in downtown Conneaut. Replacement of the viaduct on a new alignment enabled traffic to use the existing bridge while the new bridge was under construction, reducing the length of closure and detour time.  Roadway approach work and intersection work was also included in the project.

In addition to field survey, design, and construction plan preparation, the project involved extensive environmental studies and coordination.  The Conneaut Viaduct was an historic structure eligible for the National Register.  A Memorandum of Agreement was prepared containing numerous stipulations approved by the Ohio State Historic Preservation Office to mitigate the adverse effect of removing the existing structure.  Other environmental studies included extensive ecological studies due to the presence of wetlands and the high quality Conneaut Creek.  Additionally, Phase II ESA work and remedial investigations were performed on several commercial properties with documented soil and ground water contamination.
