Peotone-Beecher Road over the Exline Slough

Ciorba Group provided preliminary and final design engineering for a single span bridge replacement. A hydraulic model was completed to determine the required bridge opening and profile adjustments. Because of the presence of deep strata of unsuitable soil during the Bridge Type Study it was determined to use Geofoam material to limit the amount of earth work and to reduce future settlement of the approaches. The existing roadway was closed and traffic detoured during construction. The replacement structure consisted of 36” PPC I-beam superstructure with an 8” reinforced concrete deck will be utilized together with integral-type abutments. The project was paid for with County funds.
