This is the fifth of five bridges built at this location, an obviously favorable place to build a bridge. The first was built in 1852.
All five bridges have had nearly the same name - Smith's Bridge or Smith Bridge.
This 5th Smith Bridge was built in 1957 as part of the new freeway alignment of US 66 between Gardner and the Tri-State Tollway (I-294). It was built on a rather severe skew of 60 degrees; note how the two spans are not aligned. The new freeway and this bridge became Interstate 55 in 1960. With several subsequent rehabilitation projects, most recently in 2014, it continues to serve over 25,000 vehicles daily in each direction on Interstate 55.
NBI and IDOT treat this as two separate bridges, one southbound (IL 099-0008) and one northbound (IL 099-0009). Traffic counts and structural conditions are shown here for the southbound bridge only, and should be doubled for total traffic count on the bridge pair.
