LA 1090 is a 4.52 mile long highway through unincorporated areas northeast of Slidell. LA 1090 extends Military Road north from U.S. 190, which turns west along Gause Boulevard into Slidell. Spanning Interstate 10 with no access, LA 1090 proceeds north along Gum Bayou toward Haaswood and the town of Pearl River. The state highway concludes at the diamond interchange joining U.S. 11 (Concord Boulevard) with Interstate 59. Prior to the realignment of U.S. 11 from Main Street onto I-59, LA 1090 continued further northwest to LA 41 at U.S. 11.
