Louisiana Highway 10 a second levee to exit the Morganza Spillway. It immediately intersects LA 77 Spur, a paved highway signed as the mainline route. Motorists are directed to turn south onto this route to reach US 190. From this intersection, LA 10 turns north and becomes a paved highway once again. The route follows alongside Bayou Fordoche as it bends to the east toward the village of Morganza, located on the west bank of the Mississippi River. Here, LA 10 crosses the Kansas City Southern Railway tracks and intersects LA 1, which heads northwest through Simmesport. LA 10 turns to the southeast
Mississippi River Basin Model 1937, 1943, 1945 and 1952 were reproduced, as well as hypothetical floods at different periods of the year. Tests on individual problems were conducted until 1971 but high costs and growth of computer modelling meant that the facility was put on standby. The last use was in 1973, when a potentially catastrophic failure arose at the Old River Control Structure. The model was used to show that the untested Morganza Spillway could be opened effectively, without diverting polluted water through New Orleans and Baton Rouge, as well as identifying levees that required topping up. In 1993 the site was taken
