I-235's route forms the eastern edge of the Bricktown Entertainment District in the eastern part of downtown Oklahoma City.
I-235 was part of the original plan for the Interstate Highway System, but was one of the last to be completed. Only 3.66 miles were complete in 1978. It finally opened in 1989.
Interstate 235 in Oklahoma officially finished a major reconstruction in September 2008, which changed the section of I-235 between N.W. 50th Street on the North end and N.W. 23rd on the South end. It added a third lane and an exit lane, changing the two-lane stretch into four lanes.
