This is a Scope of Work document prepared by the Illinois Department of Transportation (ILDOT) for the complete replacement of two existing steel beam bridges at the Dongola Interchange on Interstate 57 in Union County, Illinois. The project involves replacing dual structures (existing Serial Numbers 091-0003 and 091-0004) with new five-span poured concrete deck structures on steel I-beams (Serial Numbers 091-0079 and 091-0080). The new structures will feature clear deck widths of 42 feet (44 feet 10 inches out-to-out), concrete parapets, a 4-degree 23-minute right forward skew, a 1.05 percent grade, and a back-to-back abutment length of 358 feet 9¼ inches. Both bridges will have solid reinforced concrete piers and integral abutments and will be constructed using stage construction methods. Ancillary roadway improvements include concrete approach slabs, pavement connectors, Portland cement concrete pavement and shoulders, guardrail installation, pavement marking, and seeding. The project extends approximately 920 feet along I-57 northbound and 915 feet along I-57 southbound, spanning over Cypress Road and a tributary to Big Creek.
