Indiana State Road 14

Prior to 1926 SR 14 was routed between Cannelton and St. Croix, passing through Tell City.[2] In 1926 when Indiana State Highway Commission renumbered the state roads, the SR 14 designation went unused.[3] The SR 14 designation was used again in 1931 between Fort Wayne and the Ohio state line, along a section that later became part of SR 37.[4] During 1931 or 1932, new sections of SR 14 became designated routes between the Illinois state line and SR 53, now US 231, and again from SR 43, now US 421, to Fort Wayne. In this year, SR 14 between SR 53 and SR 43 was an authorized state road.[5][6][7] In either late 1932 or early 1933, the route's western end moved to US 41, while a new authorized section of SR 14 was routed between US 41 and SR 43, passing through Fair Oaks and Gifford.[7][8] During 1933, the new authorized route was dropped from the state road system and the road between SR 13 and South Whitley was rerouted onto its modern route. Also at this time, SR 14 was authorized between the Illinois state line and US 41 and authorized from SR 55 to SR 43.[8][9] Between 1934 and 1935, the authorized section became part of the state road system, It had a driving surface of either gravel or stone.[9][10]

Between 1939 and 1941, SR 14 was rerouted from Fort Wayne to Ohio state line, passing through New Haven. This routing replaced SR 230 from New Haven towards the east. The former route of SR 14 became part of SR 37.[11][12] The section of road between the Illinois state line and US 41 was removed from the state road between 1947 and 1948.[13][14] The rest of the roadway was paved in either 1966 or 1967.[15][16] The eastern end of SR 14 was moved from the Ohio state line to the interchange with I-69 between 1993 and 1995.[17][18] The interchange between SR 14 and I-65 was opened in July 2005.[19][20] Widening along SR 14 between Scott Road and Hadley Road was completed in August 2010.[21]
