State Road 116 (SR 116) is a State Road in the northern section of the US state of Indiana. Running for about 32 miles (51 km) in a general southeast-northwest direction and it is signed east-west. The road connects Markle, Bluffton, and Geneva and passes through mostly farmland outside of cities and towns. SR 116 was originally introduced in the early 1930s routed between Markle and SR 3 north of Bluffton. The road was extended southeast to U.S. Highway 27 (US 27) in the late 1930s and early 1940s. In the mid-1940s the road was extended east to the Ohio state line, near New Corydon. This extension was removed between late 1990s and early 2000s, the east end of SR 116 was truncated to its current location at US 27.
