I-20 passes north of Barksdale AFB where it intersects I-220 with no access to the northern terminus of LA 1267 and heads east toward Monroe.

It runs 17.62 miles (28.36 km) from I-20 and Louisiana Highway 3132 (LA 3132) in Shreveport to a second interchange with I-20 in Bossier City.

Initially proposed in the late 1950s, this route was to have been only two lanes wide at a cost $29 million with a projected 2,500 to 3,000 ADT in 1964.

[4] The project was effectively canceled on October 12, 1964, when then Louisiana Representative Hale Boggs agreed to no longer seek funding for the route.

This was done in favor of focusing all efforts at funding and getting built New Orleans' Vieux Carré Riverfront Expressway.
