Illinois 99 runs northwest from Meredosia to Mount Sterling. It enters the Mount Sterling area on Pittsfield Road north of Illinois Route 107. It then overlaps U.S. Route 24 and runs west on Main Street. After about a half mile (.8 km), Illinois 99 then turns north on Cross Street, west on Washington Street, and then back north on Camden Road en route to Camden. Illinois 99 continues north (staying west of the LaMoine River) to Illinois 101 at Brooklyn, its northern termination.[3]
SBI Route 99 had been a route from West Point to Tennessee on local roads, IL 91, IL 61, and US 136. In 1935, IL 99 was dropped from those routes. In 1937, it replaced IL 104 on its current route;[4] in March 1941, it was announced that IL 99 was extended north to Brooklyn.[5]
