It would cost 202 million dollars and be 139 miles long.  It was approved by the Kansas Legislature in 1973.  Yet, somehow, it obviously did not come to pass.  
It began with Proposal No. 106—Highway Construction, a legislative interim study, called for the study of an integrated highway construction program, including the placing of toll roads in the highway system, assigning priorities for construction projects, and determining the lag time between authorization and actual construction of highways. The Special Committee on Highway Construction recommended the state explore the possibility of using state funds to construct turnpikes.
The Legislature also authorized three toll road feasibility studies. Studies were made on the U.S. 69 corridor from the Miami-Linn County line to Galena, the U.S. 59-U.S. 75 corridor from Ottawa to the Kansas-Oklahoma state line, and the U.S. 50-K-154 corridor beginning in Kiowa County and proceeding northwest to the Kansas-Colorado state line.
The Kansas Turnpike Authority was authorized to issue bonds and begin construction of the U.S. 69 facility should it be feasible. None of the proposed toll routes proved feasible.
Here is the story of the Southeast Kansas Turnpike as it appeared in the Wellington Daily News.  (July 30, 1974)
“Residents of Sumner County gathered last night to blast the proposed Southeast Kansas Turnpike, as a representative from the Kansas Turnpike was on hand to discuss the project at a meeting that drew approximately 50 concerned citizens.  
Members of the local government, Chamber of Commerce, County Commissioners, farmers, and other citizens were in attendance.  
Since the Kansas Legislature passed the bill to construct the Southeast Kansas Turnpike, meetings throughout the concerned area have been held to discuss the proposal.  
The new turnpike would call for construction to begin at the present rest area north of Wellington and cut diagonally across rich farmland to Strother Field.  
As one citizen attending put it, “It looks to me like the turnpike is being built just to serve Wichita and Strother Field.”
The present plan of construction isolates Wellington residents from use of the turnpike.  
Plans of an Industrial Park just west of the present turnpike were revealed last night by City manager A.B. Preston.  He went on to say that the new Southeast Turnpike proposal overrides all previous plans of such a project.  This in a sense would be an economical blow to Wellington.  
When asked if farmers won’t sell their land to the state, the KTA Representative stated that there was nothing he knew of that could force them to sell.  
One farmer went on record that he wasn’t selling under any circumstances.  Several others agreed and joined his verbal protest.  
The KTA Representative stated that if anybody or organization wanted to take any action, like a lawsuit, that it should be done before October at the latest.
Mrs. Ken Ratcliff represented the Southeast Kansas Landowners Association at the meeting.  Her attacks on the turnpike varied from “financially unsound” to a “politically motivated bill,” referring to Senators Pete McGill and Bob Storey being from the Winfield area and to Governor Docking, a native of the Arkansas City community.  
Mrs. Ratcliff stated that the new turnpike would see 7,500 acres of land used for right-of-way and 8,200 acres would be severance.  She was speaking of the cross-country cut between the rest area north of Wellington to Winfield.  
Ratcliff also stated that the association presently has a lawsuit filed in the Shawnee County District Court, and expected it to be turned over to the Kansas Supreme Court in the near future.  
Whatever action will be taken is not known yet, but it was clearly indicated last night that a majority of Sumner County residents would take a stand against the new proposal.”
In the following years, despite the fact that the Southeast Turnpike was found feasible and was authorized, it was held up because of court litigation and uncertain economic conditions.  It faded into history.
