Interstate 55 opened through St. Louis in 1967.1
Major construction upgraded the interchange of Interstate 55 with I-255 and I-270 between 1991 and 1994. This work coincided with a widening through 1997 of Interstate 270 between I-55 and I-44 to eight overall lanes and expansion of I-55 by four lanes from Lindbergh Boulevard (U.S. 50-61-67) to Highway A (Exit 175) at Festus.2
