When I-10 was constructed in Slidell in the 1960s, the proximity of a weigh station could not allow an exit to be built at then-US 190. Nearby Gause Road (then Louisiana Highway 1092), which paralleled the former US 190, was chosen as the I-10 exit in Slidell. After increased traffic on Gause Road and motorist confusion accessing US 190, the state of Louisiana petitioned AASHO to re-route the highway and create a new business route. At AASHO's June 1971 meeting, this request was approved. US 190 was permanently routed onto the now widened Gause Boulevard and Military Road while US 190 Business was signed along the former routing by 1975.
