Aldridge was engaged to complete a critical segment of a transmission line rebuild in the Midwest, specifically targeting the most geologically and logistically challenging structures on the project. While the majority of the line had been established, the final structures required specialized means and methods that demand a high degree of technical discipline. This portion of the rebuild was defined by massive foundation requirements and some of the most severe weather conditions the region has to offer.

On Chicago’s South Side, Aldridge supported the replacement of two aging railroad bridges located at 73rd Street and Cottage Grove Avenue. These critical structures are vital to regional transit, carrying more than 70 freight and commuter trains daily.
