Other meanings of Indiana State Road 19
Transportation
Indiana State Road 19 (SR 19) is a state highway in north-central Indiana, United States, running from U.S. Route 35 in the south to U.S. Route 24 near Logansport in the north. The route passes through rural farmland and small communities, serving as a connector between major east–west highways.
SR 19 begins at an intersection with US 35 in the unincorporated community of Mier, in Grant County. It heads north through farmland, passing through the small town of Converse in Miami County, where it crosses SR 18. Continuing north, it enters the city of Peru, where it intersects US 24 and SR 124. The highway then turns west, running concurrently with US 24 for a short stretch before ending at a junction with US 24 and SR 19's northern terminus near the Wabash River. The route is a two-lane rural highway for most of its length, with no limited-access sections.
SR 19 was originally designated in the early 1920s as part of the state highway system, initially running from the Ohio River northward. Over the decades, the route was truncated and realigned. By the 1930s, the southern terminus was moved to US 35, and the northern end was set at US 24. The route has remained largely unchanged since the 1950s, except for minor adjustments in Peru to accommodate urban development. In the 1990s, a section near Converse was widened to improve safety, but the highway retains its rural character.
The highway intersects several state and U.S. routes. In Converse, it crosses SR 18, providing access to Marion and Wabash. In Peru, it meets SR 124, which connects to the Mississinewa Reservoir. The most significant junction is with US 24, a major east–west corridor linking Fort Wayne and Lafayette. The concurrency with US 24 is brief, less than a mile, and ends at the Wabash River bridge. No interchanges exist along SR 19; all intersections are at-grade.1
SR 19 is notable for its role in the historic Michigan Road, an early 19th-century route that connected the Ohio River to Lake Michigan. Portions of the modern highway follow the old alignment, particularly near Peru. The highway also passes near the Grissom Air Reserve Base, a former Air Force base that now hosts the Grissom Air Museum. In the 1960s, SR 19 was considered for upgrade to a four-lane divided highway, but the plan was abandoned due to cost. Additionally, the route is a popular motorcycle touring road due to its low traffic and scenic farmland views.2
