History
SR 350 had its beginning in 1931 when it was designated, by Indiana State Highway Commission, from Milan to Aurora. By September 1932 SR 350 was extended west to an intersection with SR 29 (now US 421), in Osgood. The road was moved to its modern routing between Sparta and north of Milan between 1956 and 1957. Between 1957 and 1959 the road was rerouted around Mount Sinai onto the modern routing. At the same time the road was paved between the eastern in of the reroute and Wilmington was paved. The rest of SR 350 was paved between 1960 and 1961. Since the road was paved, SR 350 has not undergone any major changes.
