The only segment of US 136 that is included as a part of the National Highway System (NHS) is the segment concurrent with US 231.[5] The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation.[6] The highway is maintained by the Indiana Department of Transportation (INDOT) like all other U.S. 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 1,200 vehicles and 60 commercial vehicles used the highway daily between New Ross and Jamestown. The peak traffic volumes were 21,350 vehicles and 1,090 commercial vehicles AADT along the section of US 136 at the eastern terminus of US 136.[7]

In 1918, SR 33 was commission along what is now US 136, from Illinois state line to Crawfordsville.[8][9] The route was extended southeast to Indianapolis and the number changed to SR 34 on October 1, 1926[10] Also in that year the first section was paved, from Illinois state line to Veedersburg.[11] By 1928 the eastern part of the road from Crawfordsville to Indianapolis was paved, leaving only between Veedersburg and Crawfordsville unpaved.[11][12] In 1931, the highway was paved between Veedersburg and Crawfordsville.[13][14] SR 34 was renumbered US 136 in 1950.[15][16] U.S. 136 met its parent route, U.S. 36 at the intersection of Dr. Martin Luther King, Jr. and 16th Streets. The highway had the eastern terminus moved from downtown Indianapolis to Speedway in 1991, at an interchange with I–74 and I–465.
