Indiana State Road 237 in the U.S. state of Indiana is a discontinuous route in Perry and Crawford counties.
Route description
Southern section
The Perry County segment of SR 237, which connects to SR 37 about 1-mile (1.6-kilometre) northeast of Tell City, Indiana, provides access to Hawesville, Kentucky, via the Bob Cummings - Lincoln Trail Bridge in Cannelton, where it continues southward as Kentucky Route 69. This segment of SR 237 is 5.6 miles (9.0 km) in length and replaced an older, winding and narrow segment in 2004.
Northern section
The Crawford County segment was created on November 21, 2007, when an 8.9-mile (14.3-kilometre) segment of SR 37 from Interstate 64 at Sulphur to SR 64 at English was renumbered as SR 237. The redesignation is due to SR 37's designation being transferred to a new route (the Frank O'Bannon Highway) from I-64 to SR 64 and SR 145 between St. Croix and Eckerty.
In 2022, SR 237 was extended south along the mile-long unnumbered stretch of Old State Road 37 between I-64 and Sulphur. The route now ends at the junction of the old highway with SR 62 and SR 66.
Cancelled section
In 2008, a 2.7 mile proposed highway by-pass of Paoli, the seat of Orange County, was to carry the SR 237 designation. This project was postponed sometime around 2010 and was taken off the construction schedule in 2011.
