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 been completed. An agreement between the Highway Commission and 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.

Although the Emporia-Kansas City segment was retained, the Bureau of Public Roads left the segment between Emporia and Ottawa as a “provisional” part of the Interstate system that would not be built until traffic studies and analyses were made to determine the impact on the Kansas Turnpike. By the time the Feds were ready to okay the route, opposition surfaced on the state level. In 1963, several state legislators, especially those along the Kansas Turnpike corridor, complained that a free I-35 would divert traffic off of the Turnpike and were demanding further studies. One Wichita senator also proposed legislation to kill the project altogether. The State Highway Commission agreed to wait until 1974 before building I-35 between Emporia and Ottawa.

The plans for the section between the Lyon/Coffey county line and Ottawa also incorporated the relocation of US 75 to serve Melvern Lake, which was then also under construction. Construction on this segment of I-35 was moved up from a 1974 starting date to a November 1973 completion. The last section of I-35, between Emporia and the Lyon/Coffey county line, was completed in 1977.
