Route description

State Road 1 begins at an interchange of Interstate 275; this is I-275's only exit in Indiana. Just after the interchange there is a stop light at U.S. Route 50 (US 50). SR 1 travels 14.53 miles (23.38 km) north-northwest until it reaches I-74; just beyond I-74 it crosses Indiana State Road 46 (SR 46). SR 1 continues north until it meets U.S. Route 52 (US 52) just west of Cedar Grove. Then US 52 and SR 1 continue north-northeast for 5.78 miles (9.30 km) until they reach Brookville; here, US 52 turns west on its way to Indianapolis, while SR 1 continues north-northwest for 16.81 miles (27.05 km) where it meets Indiana State Road 44 (SR 44). SR 1 and SR 44 travel together for 0.47 miles (0.76 km) where SR 1 turns north-northeast towards downtown Connersville. North of Connersville, SR 1 travels north-northwest until it reaches Cambridge City, where SR 1 crosses U.S. Route 40 (US 40). After the intersection at US 40, SR 1 heads north-northeast. After 2.90 miles (4.67 km) SR 1 has an interchange with Interstate 70 (I-70), then heads due north towards U.S. Route 36 (US 36). SR 1 turns east onto US 36 for 1.01 miles (1.63 km), then leaves US 36 and travels generally due north until it reaches Fort Wayne. Just south of Fort Wayne, SR 1 ends at an interchange with Interstate 469 (I-469).

Northern section

On the north side of Fort Wayne at the Dupont Road exit on Interstate 69 (I-69), SR 1 begins and heads east. The road heads away from I–69, has a six-lane divided highway, passing through commercial properties. The highway narrows to a four-lane divided highway at Diebold Road and the road enters a commercial and residential properties. At Tonkel Road, SR 1 begins to curve northeast towards Leo and narrows to a two-lane highway. The route leaves Fort Wayne passing through rural farm land with houses. The road enters Leo and curves due north, onto Main Street passing through residential. North of downtown the highway curves northeast and passes through a mix of commercial and residential. As the road enters DeKalb County the road curves due north. The highway enters Spencerville passing through downtown. After Spencerville, the road curves northeast, before turning back north. The highway enters St. Joe and takes a sharp curve heading due east. The route crosses the CSX Railroad tracks and makes another sharp curve heading due north. The road heads due north, until it meets SR 8. The concurrency head east-southeast and after a 1.04 miles (1.67 km) concurrency, SR 1 leaves the concurrency heading due north. The road passing through rural farmland, with a few house, as a two-lane highway. The road enters Butler and crosses the Norfolk Southern Railroad tracks. The highway has a traffic light at US 6, in downtown Butler. The road leaves Butler heading due north, until DeKalb County Road 46, at which point the highway turns northwest. The route enter Hamilton and begins a concurrency with SR 427. The concurrency heads northeast, passing Hamilton Lake. After 0.84 miles (1.35 km), SR 1 leaves the concurrency heading due north. The highway continues to its northern terminus at US 20.[4][5][6]



SR 1 began at US 50 and Main Street in Lawrenceburg and traveled north on Main Street until Main Street became Ridge Avenue. It then followed Ridge Avenue until it met the current SR 1.

Fort Wayne

Before the new highways routed it around the city, Indiana SR1 passed through the city of Fort Wayne on a more direct route. It came from Bluffton at the south and was joined by SR3 in the (then) city of Waynedale. SR3 came from the southwest (Indianapolis) and turned east on Lower Huntington Road. The two joined in Waynedale at the junction of Bluffton Road (SR1) and Lower Huntington Road (SR3). They then continued together northward into Fort Wayne and crossed the St. Mary’s river and turned right (south) on Broadway Street for about 700 feet south. They then turned east on Rudisill Blvd. and continued to Clinton Street. Clinton Street was then US27 from Decatur, Indiana and US33 from St. Mary, Ohio. It was concurrent with US 27 and SR 3 until the I-69 interchange, where US 27 and SR 1 got on the freeway. SR 1 was concurrent with I-69 until the Dupont Road interchange. All four SR roads then continued north through Fort Wayne where they separated: SR1 north to Hamilton, Indiana, SR3 north to Kendallville, Indiana, US27 north to Angola, Indiana and into Michigan and US33 northwest to Ligonier and Elkhart, Indiana.

Nine miles south of the city of Bluffton, there is the village of Petroleum. In the late 1940s and early 1950s, Indiana highway SR1 was a three-lane highway. The three lane part started at Petroleum and continued north through Bluffton. It was a passing lane for traffic, both northbound and southbound.

Later: Before I-469 was complete, SR 1 followed Bluffton Road heading north, then turned northeast on to Baer Field Thruway, later known as Airport Expressway. SR 1 followed Baer Field Thruway until the intersection of U.S. Route 27 (US 27). SR 1 followed US 27 until the interchange with I-69, where SR 1 then exited at Dupont Road.
