McKinley Bridge Inspection and Design
This article describes the inspection philosophy for the McKinley Bridge and the methodology used for its rehabilitation, both of which kept public safety as the highest priority while maximizing the limited funding available. The bridge was owned and operated by the City of Venice, IL, and is now under the jurisdictional control of the State of Illinois, Department of Transportation. The inspection methodology followed the National Bridge Inspection Standards (NBIS) requirements; however, the inspection philosophy emphasized concentrating inspection time and resources into those portions of the bridge that were most likely to fail or most likely to become a hazard to the traveling public. The existing bridge includes a variety of common construction materials and methods, including the use of steel girders, steel trusses, timber trestles, reinforced concrete viaducts, reinforced concrete decks, wooden decks, and concrete-filled steel grid deck, which were open and closed to the traveling public at various times. The inspection resources given to each portion of the bridge were weighted based upon their structural importance, usage, and degree of deterioration. Due to the targeted use of resources, the bridge was kept operational for many years past its normal useful life. Eventually, with limited maintenance funding, it could no longer be kept in operating service, and the State of Illinois closed it to public use. Realizing that the McKinley Bridge was needed as a vital link in the St. Louis Metropolitan area, especially until the new downtown bridge is built, the State of Illinois decided to fund the rehabilitation of the bridge. All of the approach spans and deck trusses are being replaced; however, the main through trusses will remain, with the exception of the cantilever roadways. This was all based on keeping public safety as the highest priority while still making the best use of the funds available for rehabilitation.
