State Road 16 (SR 16) is an east–west state road in the US state of Indiana. The western terminus is at an intersection with U.S. Highway 41 (US 41), near Ade, and its eastern terminus is at SR 5, near Huntington. The state road runs through seven counties in northern Indiana mostly through rural farm fields and small towns.

Dating back to the early days of the state road system, SR 16 was first signed in the southern part of the state. It was moved to northern Indiana in 1926, running in two segments with the western segment being modern SR 14 from Illinois state line to Rochester and the eastern segment being modern US 224 in Indiana. During the 1930s, SR 16 was moved onto its modern routing from US 41 to SR 5. US 224 replaced SR 16 east of Huntington in the mid-1930s. The final section of SR 16 to be paved, the segment of roadway in Wabash County, was paved in the late 1960s.

Route description

History 
Before 1926 the SR 16 designation was routed between Mount Vernon and New Albany, along a similar routing as modern SR 62. In 1926 SR 16 designation was in two segments, between Illinois state line and Rochester, via Winamac, along modern SR 14. The second segment added to the state road system in 1926 was routed from Huntington to the Ohio state line, along modern US 224. The segment of SR 16 from Illinois state line to Rochester was redesignated as SR 14 between 1928 and 1929. In late 1930 SR 16 was added between US 41 and modern US 231, with the road from modern US 231 to modern SR 15 becoming an authorized addition. Between late 1930 and 1932 SR 16 between SR 29 (now US 35), in Royal Center, and SR 15 (now SR 13), near Urbana, was commissioned. In this time frame SR 16 between US 41 and SR 53, now US 231, was under construction to become a high type of roadway.

During 1932 SR 16 was commissioned between SR 15 and SR 5, while the roadway between US 41 and SR 53 was opened as a high type road surface. Between late 1932 and early 1933 SR 16 between Huntington and Markle was under construction as a high type road surface. US 224 replaced SR 16, between Huntington and the Ohio state line, between 1933 and 1934. In either 1934 or 1935 the road between US 152 (now US 231), and US 35 became an authorized addition to the state road system. The route between US 152 and US 35 was added to the state road system between 1936 and 1937. The entire roadway of SR 16 was paved between 1963 and 1964, excluding the roadway in Wabash County. The segment of roadway in Wabash County was paved in either 1966 and 1967.
