ST. CLAIR COUNTY, ILLINOIS The Illinois Department of Transportation (IDOT) procured the services of Gonzalez to provide Phase III construction inspection services for the reconstruction of Illinois Route 15 over Illinois 13 and ICG Railroad in Belleville, Illinois. The project was part of IDOT’s capital improvement plan that rated these bridges for replacement. Illinois Route 15 is a highly travelled roadway located in an expanding community. The roadway project was being built in two stages, one direction at a time, to minimize the impact to the traveling public. The complete removal and replacement of these structures was complicated by the fact that both structures, and the construction site in general, is located next to wetlands. Construction for the project had limited space to negotiate reconstruction of the structures and the associated roadwork.
This improvement consisted of removal and replacement of four bridge structures, box culvert installations, drainage improvements, earth excavation, fill placement, modified structural earth (MSE) walls, concrete pavement, asphalt pavement, signing, striping, and pavement reflectors.
