U.S. Route 41 (US 41) in the state of Indiana is a north–south US Highway that is parallel to the Illinois state line. It enters the state south of Evansville as a four-lane divided highway passing around Vincennes and traveling north to Terre Haute. In Terre Haute, it is known as 3rd Street. North of Terre Haute, it hooks east and becomes a two-lane surface road. Those wanting to stay on a four-lane divided highway can use State Road 63 to the west. It passes through Rockville, Veedersburg, and Attica before returning to a four-lane divided highway when SR 63 terminates in Warren County. It remains a four-lane divided highway until Lake County, where it becomes a main road known as Indianapolis Boulevard. It overlaps US 12 and US 20 in Hammond and exits Indiana into the South Side of Chicago. Route description US Route 41 is a largely rural road in western Indiana. It begins by crossing the Ohio River using the Bi-State Vietnam Gold Star Bridges, commonly known as "The Twin Bridges", from Henderson, Kentucky, into Evansville.

The highway reaches Interstate 64, then has three interchanges as it passes Princeton, including one dedicated to traffic coming into and out of Toyota Motor Manufacturing Indiana, ending with SR 64 on Princeton's west side addition as it heads north towards Vincennes. South of Vincennes, US 41 turns into an Interstate-standard freeway and bypasses the east side of Vincennes with interchanges and grade separations. In the middle of this bypass there is a three-level stack interchange with US 50 and US 150 eastbound, headed for Washington, Indiana; Cincinnati, Ohio; and Louisville, Kentucky. US 50 splits to the west in the city, heading for Lawrenceville, Illinois, and St. Louis, Missouri, while US 41 and US 150 continue north. North of Vincennes, the expressway turns into a four-lane divided highway, a relatively older highway coated with asphalt and a narrow median. US 41 and US 150 pass through Sullivan before entering Terre Haute. US 150 leaves the concurrency in the south end of the city, headed west towards Danville and Moline, Illinois, while US 41 continues north through Terre Haute.
