State Road 37 (SR 37) is a major route in the U.S. state of Indiana, running as a four-lane divided highway for 110 miles of its course. At one time, the route ran from the southwest corner of the state to the northeast corner. In the pre-Interstate Highway era, Indiana 37 was the most direct route between Fort Wayne and Indianapolis. Interstate 69 has supplanted it as a through route, and State Road 37 now consists of two disconnected segments. The longer segment starts at Tell City on the Ohio River and ends in Marion in north central Indiana. The other segment in northeastern Indiana runs from Interstate 469 near Fort Wayne to the Ohio state line. Route description Southern segment The southern section of Indiana SR 37 begins at a junction with SR 66 near the Ohio River in Tell City. Angling northeast, it enters the Hoosier National Forest then turns north until it meets Interstate 64 just north of State Road 62 at St. Croix. SR 37 now continues north beyond I-64, to eventually meet SR 64 near Eckerty. These two routes then run concurrently to the east for about , where just north of English SR 37 departs to the north toward Paoli and SR 64 continues east toward Marengo. Just prior to reaching Paoli SR 37 leaves the National Forest. Once in town the route has a very brief (two block) concurrency with US 150 and SR 56 to loop around the town square before it leaves to the north, heading for Orleans and Mitchell. Until reaching Mitchell, SR 37 is a two-lane rural route with relatively light traffic. However, from this point north to Indianapolis, the character of the road changes to become a major rural arterial route. At Mitchell the 4-lane divided highway begins with a short concurrency of SR 60 on SR 37 as both routes skirt the edge of town. From there, SR 37 continues north to US 50 on the outskirts of Bedford. US 50 and SR 37 then run concurrently, curving northeast to cross the East Fork of the White River before turning north to bypass the center of the city on its west side. After US 50 leaves to the east, SR 37 proceeds northward to Bloomington, where it now meets up with the new southern extension of Interstate 69 on that city's southwest side. From that point in
