The original structure was built in 1959 and widened with a new deck in 1982. It consists of a four-span structure with continuous wide-flange beams with pile bent pier abutments and reinforced concrete columns. The decision to replace the bridge comes from IDOT, due to the low clearance, the cause of many accidents on I-74.
“IDOT has realized the value hot-dip galvanized steel can offer in the longevity of their bridge projects and we continue to see galvanizing specified more often.”
The replacement structure consists of a two-span bridge that measures 214 feet from back-to-back of abutments, with an out-to-out width of 75 feet – 10 inches. The bridge carries two, 14-foot traffic lanes, 8-foot outside shoulders, a 12-foot left-turn lane, and a 10-foot-wide multi-use path on the east side of the structure. The structure was constructed utilizing stage construction to maintain one lane of traffic in each direction.
The superstructure consists of a cast-in-place concrete deck supported by hot-dip galvanized composite plate girders. The decision to hot-dip galvanize the steel in this bridge comes from the value of longevity that galvanizing provides.
