Project Description:  The rehabilitation of the I-70 bridge over the Wabash River in Vigo County required extensive research in order to develop a rehabilitation project that would meet the needs of the State while maintaining traffic during construction. The bridge is 1,961 feet long with 21 spans consisting of steel rolled beams and steel plate girders with a reinforced concrete deck. Preliminary design included multiple options for widening the existing bridge which compared construction cost, user cost, and impacts to sensitive environmental areas around the Wabash River. United successfully developed a project that met all of this criteria while also meeting the user demand for continuous use during construction.

Approximate Project Cost:  $12,000,000

Breadth of Services Provided:  Bridge Inspection, Scope Development, Value Engineering, Environmental Document, Supplemental Topographic Survey, Highway Design, Bridge Design, and Regulatory Permit Acquisition.
