this stretch is already a 4-lane partially access-controlled expressway, its present configuration still falls well short of Interstate freeway standards in that it contains numerous at-grade intersections, including 19 with traffic signals. The section between the recently built I-69 interchange north of Victor Pike in Bloomington to the curve south of Epler Avenue in Indianapolis will be upgraded to have full access control, and from that point a brief new terrain connection will be built due north to a new system interchange at I-465/I-74. The segment between Bloomington and Martinsville was completed on October 31, 2018 and the section between Martinsville and Indianapolis is scheduled to be fully completed in 2024. Once construction is completed, SR 37 will be decommissioned between Bloomington and Fishers as it overlaps with I-69. Beginning January 2, 2021, a portion of SR 37 was closed in Martinsville to allow for quicker construction of I-69 in the area. Construction was completed 11 months later, and the road was re-opened to traffic on December 20, 2021. Major intersections Related route State Road 37A (SR 37A) ran from Indianapolis to Noblesville from 1959 until the 1970s. Beginning sometime between 1957 and 1959, the designation SR 37A was first used for the old routing of SR 37 between Indianapolis and Noblesville. The southern end of the road was moved to SR 100 in late 1963 or early 1964. In late 1964 or early 1965 the route was shortened at the north end, with the new end being at an intersection with SR 32 and SR 38. In late 1969 or early 1970 the designation of SR 37A in Hamilton County was removed. The state highway commission removed the last segment of SR 37A in Marion County in either late 1972 or early 1973. SR 37A (Allisonville Road) began at its southern terminus with its parent route, SR 37 (now Binford Boulevard), near the Indiana State Fairgrounds. The route traveled northeast crossing 52nd and 56th streets, Kessler Boulevard East Drive, and 62nd, 65th, 71st, 75th, and 79th streets, before it reached an intersection with East 82nd Street near Castleton Square Mall. The route then interchanged with Interstate 465 (I-465 Exit 35), followed by intersections with 86th, 91st, and 96th streets, then crossed into Hamilton County and the town of Fishers. In Fishers, the route intersected East 106th Street near Indianapolis Metropolitan Airport. The route intersected 116th, 126th, and 131st streets,
