I-35 was first envisioned to parallel US 50/50S to Newton, then follow US 81 and US 177 south to the Oklahoma border.� By the time the interstate highway act was passed in 1956, the Kansas Turnpike had completed.� An agreement between the Highway Commission and the the Bureau of Public Roads in December 1956 designated the Turnpike south of Emporia as part of I-35.� The segment between Emporia and Newton was removed, but the segment along US 81 north of Wichita was extended north to Salina as I-35W.

The segment between Olathe and Shawnee was designated in January 1950 as part of US 50 and completed as a two lane roadway by 1953. The bypass around Emporia was designated as part of US 50S in October 1951. In February 1957, two separate resolutions designated I-35 between Ottawa and Olathe (as US 50) and between Shawnee and K-10 at Southwest Boulevard in Kansas City (as US 169). The entire route between Southwest Boulevard and Ottawa was complete as a freeway by 1962.

By 1968, the Emporia bypass, and the segment from Southwest Boulevard to 7th Street, had been completed. In November of 1968, the Highway Commission passed a resolution designating the segment of I-35 between Ottawa and Emporia, along with relocations of US 75 and K-31. The segment between 7th Street and the Missouri border was completed by 1971. I-35 between Ottawa and K-130 north of Neosho Rapids was completed by 1974. The re-located US 75 was completed by 1975. The last segment of I-35 was complete by 1976.
