  State Road 109 (SR 109) is a north–south discontinuous State Road in the US state of Indiana. The southern segment of the highway runs from U.S. Route 40 (US 40) in the town of Knightstown north to SR 9 in Anderson. The northern segment of SR 109 runs from US 30 in Columbia City northerly to US 33 in Wolf Lake. The total length of the highway is 31.769 miles (51.127 km), including the southern segment which is 20.129 miles (32.394 km) and the northern segment at 11.640 miles (18.733 km). The first usage of the SR 109 designation dates back to 1934 with the original routing being between Columbia City and Wolf Lake. A southern section was added in 1940 between Knightstown and the Hancock–Madison County line. The southern segment was lengthened in the early 1940s and once again in the early 1950s extending the road north to just north of Anderson. The northern segment of SR 109 was shortened in Columbia City during the early 1970s. SR 109 in Madison County was moved to a new routing in the late 1990s.
  
  ## Route description
  
  ### Southern section
  
  The southern segment of SR 109 begins at an intersection between Main Street (US 40) and McCullum Street in the town of Knightstown. SR 109 heads north along McCullum Street before leaving the town limits and curving towards the northwest. The road has an interchange with Interstate 70 (I–70) in rural Henry County. SR 109 enters Hancock County passing through the town of Wilkinson. After Wilkinson, SR 109 has a four-way stop with SR 234, before entering Warrington. In Warrington the road becomes north-south once again, passing through rural Hancock County, before entering Madison County. SR 109 passes through a four-way stop with SR 38, west of Markleville, before an intersection with US 36. North of US 36, SR 109 parallels a CSX railroad track, before crossing over the railroad tracks south of Anderson.

  ## History
  
  The Indiana State Highway Commission authorized a state road following modern SR 109, between Columbia City and Wolf Lake, in 1934. Construction started in 1935 on the authorized segment with it being completed by 1942. A segment of state road was commissioned, between Knightstown and the Hancock–Madison County line, in March 1940. This section of roadway was originally planned as SR 7, but became a southern segment of SR 109. The northern end of the southern segment was moved north to SR 32 in Anderson in July 1941. Between late 1950 and early 1951 the northern end of the southern segment was moved north to an intersection with SR 9, just north of Anderson. The southern end of the northern segment was moved north to an intersection with the new alignment of US 30, just north of Columbia City, in late 1970 or early 1971. A new alignment for SR 109, from south of US 36 to Anderson, was constructed between 1997 and 1999.
