Illinois Route 33 runs east-west in southeastern Illinois, connecting the Effingham area to points east. The western end is a little west of Effingham, near Beecher City, and the eastern end dives south along the Wabash River to end just across that river from Vincennes, Indiana.
The western end of Illinois 33 is at Illinois 128 near Beecher City (not to be confused with Beecher, which is in Will County):

The southeastern end of Illinois 33 is strange; having passed under US Route 50 alongside the Wabash River, Illinois 33 reaches the bridge carrying Indiana 441 out of downtown Vincennes into Illinois, and Illinois 33 bends northwest as a sort of access road to US Route 50.
