State Road 63 (SR 63) in the U.S. state of Indiana is a north–south route in the western portion of the state. Until mid-2008, it covered a distance of just over 96 miles (154 km), but now is a discontinuous route. For 63 miles (101 km), from the city of Terre Haute until it rejoins U.S. Route 41 (US 41) near Carbondale, it is a four-lane divided highway and replaces US 41 as the major north–south artery in this portion of the state.
Only the divided highway section of SR 63 from US 41 in Terre Haute to US 41 north of Attica is included as a part of the National Highway System (NHS), a network of highways 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 and US highways in the state. The department tracks the traffic volumes along all state highways 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 700 vehicles and 40 commercial vehicles used the highway daily near the southern terminus. The peak traffic volumes were 14,900 vehicles and 1,980 commercial vehicles AADT along the section of SR 63 immediately north of the US 41 in Terre Haute.
