Providing both a bypass for I-20 around Shreveport and Bossier City and part of the link between I-49 north to Texarkana, Arkansas and south to Alexandria, Interstate 220 is a 17 mile long loop. The freeway branches north from I-20 and LA 3132 (Inner Loop Expressway) and spans Cross Lake to I-49 in North Shreveport. I-220 turns east at U.S. 71 and crosses the Red River ahead of a retail corridor in north Bossier City. Eastern reaches of the freeway loop serve an array of industrial parks, subdivisions and Louisiana Downs Casino And Racetrack.
The systems interchange joining Interstate 220 with I-49 North Segment K2 at North Shreveport was completed on October 17, 2018. The exchange officially opened to traffic following a celebration attended by Governor John Bel Edwards and several state and local officials. Construction on Segment K2 started in 2014. The $142 million project included rebuilding I-220 and adding auxiliary lanes between Exit 5 (LA 173 / Hilry Hickaby III Avenue) and Exit 7A (U.S. 71 / North Market Street).1
Interstate 49 was formally routed alongside both I-220 west from North Shreveport to I-20/LA 3132 (Inner Loop Expressway), and on I-20 east from I-220 to the four level interchange with I-49 at Pete Harris Drive/Allen Avenue by action of American Association of State Highway and Transportation Officials (AASHTO) on May 21, 2019. Trailblazers for I-49 posted along both I-20 and I-220 provide route continuity between the separate sections leading into Shreveport.

The bypass loop of Shreveport was part of the urban Interstate numerology submitted to the American Association of State Highway Officials (AASHO) by the Louisiana Department of Highways. It was initially numbered as Route A20, with Route B20 assigned to the planned loop around Monroe. These changed to I-220 and I-420 respectively per instructions from AASHO on July 2, 1958 and were approved on November 10, 1958.
The last section of Interstate 220 completed was the bridge over Cross Lake in 1988. Topping out at 24.6 feet, the span extends 10,230 feet between Exits 2 and 4.1
