# Indiana State Road 15

State Road 15 (SR 15) is a north–south state road in northern part of the US state of Indiana. Its southern terminus is at U.S. Highway 35 (US 35) and SR 22 near Jonesboro and its northern terminus is the Michigan state line, north of Bristol, where the roadway continues north as M-103. It is a surface highway that mostly passes farm fields but passing through a few cities of Marion, Wabash, Warsaw, and Goshen. Running for 94.835 miles (152.622 km) through the state, SR 15 is maintained by the Indiana Department of Transportation (INDOT).
Dating back to the before the state road system, the corridor that SR 15 takes today was part of the Hoosier Dixie Highway. The first numbered route along the modern SR 15 corridor was SR 27, while SR 15 ran from Indianapolis to near Michigan City. SR 15 was moved to its modern routing in late 1926, running from Marion to Goshen. During the late 1920s, SR 15 was moved onto its modern routing between Milford and New Paris. In 1930 the road was extended from Goshen to Michigan. The route from Wabash to SR 114 was moved to its modern route in the mid-1930s. In late 1940s and early 1950s, SR 15 was rerouted between La Fontaine and Wabash, while the route was extended south from Marion to Jonesboro.

## Route description

SR 15 begins as an intersection with US 35/SR 22, near Jonesboro. The road heads northwest, crossing a railroad track before entering Marion, passing east of Indiana Wesleyan University. North of the university SR 15 turns west on 38th street before SR 15 turns north concurrent with SR 9. The concurrency passes through commercial properties, on Western Avenue, before bending onto Baldwin Avenue, passing over a railroad track. While SR 15 and 9 are concurrent SR 15 has its highest annual average daily traffic (AADT) at 27,097 vehicles per day on average measure in 2016. North of the tracks the street passes through residential properties before the landscape becomes commercial properties, where the road curves to the northwest. SR 15 turns northwest, onto Wabash Avenue, while SR 9 continues northeast. The road leaves Marion passing through rural Grant County, crossing the Mississinewa River, before entering Wabash County. In Wabash County SR 15 passes agricultural land, parallel to a railroad track, passing through an intersection with SR 218 in La Fontaine. Past La Fontaine the road passes through an intersection with SR 124 before entering the city of Wabash.
The road enters Wabash SR 15 and the railroad tracks separate, before an intersection with SR 13. At this intersection SR 13 and SR 15 head north concurrent, passes through commercial properties, before crossing over the Wabash River. North of the river the street continues north through commercial properties, before entering the Downtown Wabash Historic District. In the historic district the concurrent ends with westbound SR 15 turning onto Market Street, while eastbound SR 15 uses Canal Street. While concurrent with Canel Street SR 15 has its lowest AADT at 3,123 vehicles per day on average measured in 2016. The one-way pairs end with SR 15 heading north on Cass Street and leaves the historic district. SR 15 heads north, passing a landscape of residential neighborhood, before bending to become northwest-southeast and having an intersection with US 24 Business. North of US 24 Business the road has an intersection with US 24 before leaving the city of Wabash and reentering rural Wabash County.

The concurrency heads east for a few blocks before it ends with SR 15 turning northeast, while SR 120 continues east. The road leaves Bristol and passes through wooded area, crossing over the Little Elkhart River, and passes over the Indiana Toll road, Interstate 80 and Interstate 90. After bridging over the toll road is the access road to the toll road, followed soon after the road ends at the Michigan state line.

## History

In 1915, prior to a state road system in the state of Indiana, the Hoosier Dixie Highway ran along some of what later became part of SR 15. The Hoosier Dixie Highway ran from the Ohio state line, in West Harrison, to the Michigan state line north of Goshen. When the state of Indiana started the state road system the SR 15 designation went from Indianapolis to SR 25, east of Michigan City, passing through Logansport and La Porte. At this time the modern corridor of SR 15 was part of SR 27. In 1926 the Indiana Highway Commission renumber most roads with this renumber the SR 15 designation was moved east to its modern corridor. This highway ran from Marion to Goshen, routed along SR 13 between Wabash and North Manchester. Then the SR 15 designation turned west along modern SR 114 to a point south of Silver Lake where SR 15 turned north along its modern route. At this time the original route of SR 15 became part SR 29. During 1928 the roadway between Milford and New Paris was rerouted to its modern route. This realignment straightened the road and eliminated two railroad crossings with the Big Four Railroad. In 1930 the designation was extended north to the Michigan state line. An authorized state road along modern SR 15 between Wabash and SR 114, just south of Sliver Lake, was added in late 1932. This route became part of the state road system in 1934. Within the next year the entire route of SR 15 became a high type of driving surface. Between 1949 and 1950 SR 15 was rerouted between La Fontaine and Wabash, passing through Treaty. The road was extended south from Marion to Jonesboro, along the former route of SR 21, in either 1950 or 1951.

## Future

SR 15 has two projects that will change some of its routing in Elkhart County. The first is injunction with the US 33 bypass of downtown Goshen, when completed SR 15 will be moved west of the Elkhart County Courthouse onto Third Street. This route is currently a truck route around downtown Goshen. The second project will take place during 2018 and will sign a truck route to avoid downtown Bristol. The Truck SR 15 will be added a few blocks east, of modern SR 15.
