State Road 101 marker

State Road 101 in the U.S. state of Indiana is a north–south state highway in the eastern portion of Indiana that exists in four sections with a combined length of 79.42 miles (127.81 km).

Only the segment of SR 101 that is concurrent with the U.S. Route 33 (US 33) are included as a part of the National Highway System (NHS). The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation. The highway is maintained by the Indiana Department of Transportation (INDOT) like all other State Roads in the state. The department tracks the traffic volumes along all state roads as a part of its maintenance responsibilities using a metric called average annual daily traffic (AADT). This measurement is a calculation of the traffic level along a segment of roadway for any average day of the year. In 2010, INDOT figured that lowest traffic levels were the 710 vehicles and 60 commercial vehicles used the highway daily between SR 124 and US 33. The peak traffic volumes were 5,740 vehicles and 450 commercial vehicles AADT between Sunman and I–74.

The southernmost portion of the route is 0.48 miles (0.77 km) long and connects SR 156 in Switzerland County with Kentucky Route 1039, which connects to Interstate 71 and U.S. Route 42 near the Kentucky Speedway by crossing the Ohio River on the Markland Dam. Before expansion of the Speedway and extension of KY 1039, the route connected to Kentucky Route 1188, which ended just past the Ohio River at U.S. 42.
