Route description 
Illinois 33 is a largely rural state highway. It runs east from near Beecher City to meet Illinois Route 32 in Shumway. Through Effingham it is Fayette Avenue and Willow Street. Continuing to the southeast, it runs through the small towns of Dieterich and Wheeler. It then travel through Newton and joins with Illinois Route 130 and goes north. Two miles north of Newton it branches off and travels east through Oblong and then to Robinson. In Palestine, the road runs along Washington and Franklin Streets before turning south on Jackson Street and leaving the city.
Illinois 33 continues south, parallel to the Wabash River and beneath U.S. Route 50. There is no intersection at this point. Illinois 33 then travels west (along the old alignment of U.S. 50) and then back north to meet its terminus at a full interchange with U.S. 50.
SBI Route 33 originally was Effingham to Gordon (near Robinson). In 1937, 1941 and 1948, extensions were made east to Palestine, west to Beecher City, and then south to U.S. 50 to complete the route.
