Day 2 of the whirlwind trip took us around the Shreveport freeway system, northward along new Interstate 49 to Arkansas, around Texarkana on the new I-369 and AR 549 freeways, and northeast to a revisit of the Little Rock Interstates. Meandering southeastward, we crossed the doomed Clarendon Bridge over the White River toward U.S. 49 through Helena-West Helena into Mississippi. Zigzagging southward, we ended up in Vicksburg.
Interstate 220 provides a through route bypass of Shreveport, traveling 17.62 miles through northern reaches of the city. The freeway utilizes a long viaduct over Cross Lake, which was the last facet of roadway to open for the route. Construction on the span commenced in January 1984, and it was originally slated for completion in 1986. Delays pushed back the opening date until April 10, 1989.1
A 1987 Shreveport inset from a Gousha atlas shows the Cross Lake bridge for Interstate 220 still under construction.
Interstate 220 east over Cross Lake. The bridge features a unique drainage system, where water flows toward the center of the span. Collected water departs a central pipe system for a concrete holding pond at the north side of the lake. This drainage method protects Cross Lake from chemicals and other pollutants. Cross Lake is the source of Shreveport’s drinking water.1
The east end of Interstate 220 consists of a half-built directional cloverleaf interchange with six stubs left over from an unconstructed extension southeast through Barksdale Air Force Base.
Grading for a loop ramp from unconstructed I-220 west to I-20 west is evident. Our 2008 blog post on Interstate 49 in Louisiana referenced a possible extension of the I-220 freeway southeast to the planned corridor of Interstate 69.
