Elevated lanes continue along I-310 south to a point two miles beyond Exit 2 (U.S. 61). The Interstate 310 viaduct in conjunction with Interstate 10 between Exits 210 (Interstate 55) and 220 (Interstate 310), and the southernmost 23 miles of Interstate 55 represent the longest continuously elevated highway in the world at 38 miles.
