This section of Old US90 lies between IH10 and Louisiana State Highway 3112 in Toomey. Originally US90 came from the south, made the gradual turn indicated in the images below and continued to the northeast. After the completion of the IH10 bridge over the Sabine River in the 1950's, and as part of the diversion of traffic a temporary set of connection lanes was constructed. The 2 lane section of LA3112 from LA109 to LA3112's transition to a divided 4 lane is the original US90 alignment. The northern half of US90's curve was removed in favor of the connection lanes.
