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).

Route description[edit]

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).[2] The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation.[3] 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.[4]

Southern section[edit]

The southernmost portion of the route is 0.48 miles (0.77 km) long and connects SR 156 in Switzerland County with Interstate 71 U.S. Route 42 in Kentucky by crossing the Ohio River on the Markland Dam.[5][6]

The second portion of SR 101 is 17.47 miles (28.12 km) long and is within Ripley County. This sections of SR 101 begins at U.S. Route 50 (US 50) and heads north towards Milan. The road passes through rural farmland with a few houses as a two-lane highway. The road turns towards the northeast just south of SR 48. After SR 48 the highway turns back due north. This section ends at an interchange with Interstate 74 (I–74) in Penntown.[7][6]

North central section[edit]

The third portion of SR 101 is 16.44 miles (26.46 km) long and starts at US 52 and SR 1 in Brookville. SR 101 runs concurrent with SR 1 north and then SR 101 heads northeast, leaving SR 1. The highway curves around Brookville Lake and continues due north towards Liberty. The road crosses into Union County and turns northeast again, ending at an intersection with US 27 and SR 44 in Liberty.[8][6]

The fourth and final portion is 45.03 miles (72.47 km) long and has its southern terminus at SR 124 in southeastern Adams County and heads north passing through farmland. The road enters Pleasant Mills and has a short concurrency with US 33. North of Pleasant Mills, the road crosses over the St. Marys River. After the river, the road enters Rivare and starts a concurrency with US 224. The concurrency heads west leaving Rivare heading towards Decatur. The concurrency end when SR 101 turns back north and US 224 continues towards the west. SR 101 crosses into Allen County and has an intersection with US 30 near Townley. After US 30, the road has an all-way stop at old SR 14, now known as Dawkins Road. After Dawkins Road the road crosses the Norfolk Southern Railway. Then the road enter Woodburn and makes a sharp curve heading towards the east, followed by another curve back north.
