When Pennsylvania first legislated routes in 1911, what would become PA 68 was designated as Legislative Route 243 between the Ohio border and Rochester, Legislative Route 78 between Rochester and Butler, Legislative Route 214 between Butler and Clarion, and Legislative Route 98 in a portion of Forest County.^[7] PA 68 was designated in 1927 to run from the Ohio border in Beaver County northeast to US 6/US 119/US 120/PA 6/PA 7 in Kane, running along its current routing to Clarion before continuing to Kane. At this time, the entire route was paved between the Ohio border and Clarion except for a portion between Rimersburg and Sligo. Between Clarion and Kane, the entire route was unpaved except for a portion near Marienville and to the southwest of Kane.^[8] A year later, the route between Rimersburg and Sligo was paved.^[9] By 1930, PA 68 paved between US 322 northwest of Clarion and Paint Mills, Arthurs and Snydersburg, and around Leeper while the state highway was under construction between Paint Mills and Arthurs, Snydersburg and southwest of Leeper, and the Clarion/Forest county line and Roses.^[10]

In the 1930s, the entire length of the route between Clarion and Kane was paved.^[11] PA 68 was extended northwest from Kane along a paved road to PA 59 in Kinzua in 1935.^[11][12] In 1961, the Pennsylvania Department of Highways approved moving the northern terminus of PA 68 to US 6 in Kane, with PA 321 replacing much of the route north of Kane. The former northern terminus at PA 59 in Kinzua was inundated with the creation of the Allegheny Reservoir.^[13][14][15] In 1970, the north end of PA 68 was cut back to its current location at US 322 in Clarion, with the route between US 322 northwest of Clarion and US 6 in Kane replaced by a rerouted PA 66.^[15] This change was made to keep truck traffic away from the Toby Bridge, which had a 15-ton weight limit and collapsed from an incident with a truck in 1969. Northbound trucks were instead directed to follow I-80 and PA 66 to avoid the bridge along the former PA 68 alignment.^[16]

Pennsylvania Route 68 Truck is a connector truck route that directs motorists to PA 68 while avoiding PA 989. Trucks are advised to follow Big Knob Road to avoid a 10 ton weight limit on PA 989 north of this intersection.^[17]
