In Indiana, it is a state road that enters the state at the Ohio state line between Willshire, Ohio, and Pleasant Mills, Indiana. The 106.217 miles (170.940 km) of US 33 that lie within Indiana serve as a major conduit. All of the highway is listed on the National Highway System. Various sections are rural two-lane highway, urbanized four-lane divided expressway and the Lincoln Highway. The northernmost community along the highway is Elkhart. The highway ends at an interchange in southern Elkhart after serving the northeastern region of Indiana. US 33 passes through farm fields and urban areas.

US 33 was first designated as a U.S. Highway in 1937. A section of the highway originally served as part of the Lincoln Highway, a connection between Fort Wayne and South Bend. US 41 replaced some the original State Road 2 (SR 2) designation of the highway which dated back to the formation of the Indiana State Road system. SR 2 ran from Illinois state line through South Bend to Elkhart and ended at the Ohio state line. Realignments and construction projects have expanded the highway to four lanes.
