The expansion of I-41 north of the Zoo Interchange required the replacement of many bridges, including the bridge crossing Underwood Creek. County Materials’ Prestressed Bridge Girders were specified for the structure. County Materials manufactured and delivered 208 prestressed concrete bridge girders, using multiple production facilities to meet the project’s aggressive delivery schedule. Arriving on site ready to install, prestressed girders can reduce the impact of a major roadway project on the surrounding business and residential community by accelerating construction timelines.
