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 Indiana 37 now consists of two disconnected segments. The segment in northeastern Indiana runs from the Ohio state line to Interstate 469 near Fort Wayne. The other segment starts at Tell City on the Ohio River and ends in Marion in north central Indiana.
The southern section has its northern terminus just south of Marion at a junction with State Road 9. It runs south and southwest, passing near Elwood. From here it continues south to Noblesville where it becomes 4-lane divided highway. After this it merges with Interstate 69 near Fishers, joining Interstate 465 northeast of Indianapolis, running along the portion of I-465 concurrent with US 31, US 36, US 40, US 52, US 421, and IN 67 (from exits 42 to 46).
It then departs Interstate 465 on the south side of Indianapolis at Exit 4 where it is a 4-lane divided highway until its southern junction with IN-60 75 miles later. The road runs south and southwest through Martinsville, Bloomington, Bedford and Mitchell.
The next 45 mile segment is part of the above southern section but is a 2 lane rural route that has a lot less traffic. It begins in Orleans and runs through Paoli and the Hoosier National Forest. At English, it turns west along State Road 64 for about 8 miles (13 km) west before turning south at Eckerty (along the Frank O'Bannon Highway), meeting its southern terminus at the junction with State Road 66 on the Ohio River in Tell City.
The northern section begins at the Ohio state line near Harlan, where it continues east as State Route 2. Indiana 37 runs southwest approximately 20 miles (32 km) to end at a junction with Interstate 469 on the northeast side of Fort Wayne.
Due to the fact that SR 37 is already a 4-lane limited access highway (although it is still well short of freeway standards as it contains many at-grade intersections, including 19 traffic lights) it will be upgraded with some work to become Interstate 69 from north of Victor Pike in Bloomington to the curve south of Epler Avenue in Indianapolis, where I-69 will run straight north to Interstate 465.
Frank O'Bannon Highway
In recent years, Indiana's official state highway maps have shown the 10-mile (16 km) extension of the Frank O'Bannon Highway (named for the late former governor) between Interstate 64 at St. Croix and Indiana 64 at Eckerty numbered as Indiana 145. However, when the extension opened in November 2007, the signs proved that the Indiana Department of Transportation (INDOT) had a change of heart.
At I-64 Exit 79, where Indiana 37 once turned east and ran concurrent with the interstate for eight miles (13 km) before continuing its northern journey, the route now continues north approximately 10 miles (16 km) to Eckerty. At Eckerty, westbound Indiana 64 continues the new route to the northwest for a short distance (less than a mile) before meeting the existing Indiana 145, which continues north across Patoka Lake to French Lick. The new roadway thus creates a "straight shot" from Indiana 37's southern terminus at Tell City to French Lick, West Baden and the new casino. It also will reduce travel time for those traveling to Indianapolis.
For its part, Indiana 37 now turns to the east and is concurrent with Indiana 64 from Eckerty to English, where it exits the eastbound highway and rejoins the old route. The old, winding stretch of 37 from I-64 at Exit 86 north to English has been renumbered as Indiana 237.
Its original route through Indianapolis started with Binford Boulevard, which continues southwestward from I-69 at the interchange with I-465. Binford Blvd. then ends and traffic merges onto East Fall Creek Parkway North Drive. State Road 37's traffic followed this route still southwestward, then turned to the west onto East 38th Street. SR 37 followed this to North Meridian Street, and turned south, joining with the traffic from U.S. Highway 31 before it too was routed onto I-465. The route continued south to East North Street for one block and then southward onto North Pennsylvania Street for southbound traffic, and northbound traffic was one block to the east on North Delaware Street. The traffic then joined together on Madison Avenue, south of downtown, headed in a south-southeast direction. State Road 37's old route then continued directly south on South East Street to I-465 west to its current exit, #4, Harding Street.
Bluff Road, a south-southwest-bound street on the south side of Indianapolis was sometimes shown on some road maps as "37A", because State Road 37 used to follow this route, but does not interchange with I-465/SR 37, nor does it have an intersection with State Road 37 south of that; it stops just short of the road in a dead end (though there is access to 37 via nearby Wicker Road immediately before that dead end). Allisonville Road, a north-northeast bound street on the opposite side of Indianapolis, was also shown as State Road 37A, but the road does terminate at State Road 37 north of the city and at Binford Blvd. at its south end.
Originally, SR 37 ran from its current northern terminus of the southern section concurrent with SR 9 from south of Marion to Huntington. From Huntington to Fort Wayne the highway as concurrent with US 24. The road passed through Fort Wayne on Jefferson Boulevard, then head north on Anthony Boulevard. SR 37 turned northeast onto Crescent Avenue, Crescent Avenue became Maysville Pike, later Maysville Road. The route followed Maysville Pike to its current southern terminus of the northern section, at I–469.
