Louisiana Highway 3019
Louisiana Highway 3019 (LA 3019) runs 0.53 mi in an east–west direction primarily along Veterans Highway in New Orleans (Orleans Parish).

LA 3021 is a vestige of the original plans for the Eastern Expressway, incorporated into the route for I-10 by the time of its construction in the 1960s, which would have connected Eastern New Orleans with North Claiborne Avenue via an expressway in the median of Elysian Fields Avenue. In the pre-1955 state highway system, the proposed route was given the temporary designation of State Route C-2200, changed to LA 3021 in the 1955 Louisiana Highway renumbering. The Elysian Fields Avenue segment, as well as a segment of Morrison Road that is now LA 1253, were ultimately left out of the expressway plans.
