Description 

Harold Bartholomew first envisioned an elevated highway along Third Street in 1928. It took seven years to build the 2.3 mile Third Street Expressway and hundreds of buildings were wiped out. It opened on October 15, 1955. It was later designated to carry I-55. In 2014, I-44 was extended to the new Stan Musial Bridge and it now carries 44 as well. This area underwent significant reconstruction and rehabilitation in 2016-2017 to replace the outmoded ramps to and from the Poplar Street Bridge.
