Indiana State Road 37
From Wikipedia, the free encyclopedia
State Road 37 (SR 37) in the U.S. State of Indiana at one time ran from the northeast of the state to the south end. In the pre-Interstate Highway era, Indiana 37 was the most direct route between Fort Wayne and Indianapolis, although Interstate 69 has supplanted it and some other highways as through routes. It remains as the principal link between Indianapolis and Bloomington.
The Indiana Department of Transportation has decommissioned some sections of Indiana 37 where it coincided with existing highways and inside the freeway loops surrounding Fort Wayne and Indianapolis. It now consists of two discontinuous segments:
- A 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 to end at a junction with Interstate 469 on the northwest side of Fort Wayne.
- A 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 and Noblesville. It merges with Interstate 69 near Fishers, joining Interstate 465 northeast of Indianapolis, running along the portion of I-465 multiplexed with US-31, US-36, US-40, US-52, US-421, and IN-67 (from exits 42 to 46) and departing Interstate 465 on the south side of Indianapolis at Exit 4. It runs south and southwest through Martinsville, Bloomington, Bedford, Mitchell and Paoli. It then continues south through the Hoosier National Forest and merges with Interstate 64 for about 7 miles west before continuing southwest to its southern terminus at the junction with State Road 66 on the Ohio River just north of Tell City. Indiana 37 previously continued south to the Kentucky state line at Cannelton, Indiana.
SR 37 will be upgraded on the spot 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.[1]
