Interstate 135 Kansas

North End
South End


Interstate 135 overlays U.S. 81 from the Kansas Turnpike (I-35) and Wichita in south central Kansas to Salina and Interstate 70. It is the fourth longest three-digit route within the Eisenhower Interstate System, following Interstates 476, 495 in Massachusetts and 287.

The freeway bisects Wichita mostly along the elevated Canal Route, a seven mile stretch paralleling or running above the culverted Chisholm Creek Canal. Accommodating six overall lanes, 95,700 vehicles per day (vpd) were recorded along a busy stretch north of U.S. 54 & 400 (Kellogg Avenue) to the east of Downtown Wichita in 2015.

Interstate 135, U.S. 81 and K-15 along the Canal Route through Wichita. The flood control basin and drainage ditch network feeds into the canal running between the north and southbound roadways of the freeway. Photo taken 10/20/03.

Remaining suburban through Park City and Valley Center, Interstate 135, U.S. 81 & K-15 leave the Wichita metropolitan area for a rural course to Newton and a brief overlap with U.S. 50. K-15 splits to the north from there as I-135 shifts northwest to McPherson and the north end of the K-61 expressway connecting with Hutchinsin.

Turning northward again, Interstate 135 & U.S. 81 continue by Lindsborg to Salina. The freeway generally bypasses the city of nearly 50,000 to a rural cloverleaf interchange with I-70 & U.S. 40. I-135 ends there, with U.S. 81 extending north as a freeway then expressway to Concordia.

High Priority Corridor

Interstate 135 in its entirety, along with the route served by U.S. 81 and U.S. 77 north to Sioux City, Iowa, is part of High Priority Corridor 23: Interstate Route 35 Corridor.


Interstate 135 was originally designated as Interstate 35W, representing a main route north from I-35 as it turned northeast from Wichita along the Kansas Turnpike to Emporia. The first section of the freeway was under construction around McPherson in 1968, with work on most of the remaining freeway getting underway by the early 1970s.1

The Canal Route section of I-135 through Wichita cost $32 million, with work there starting in 1971. This section included the most expensive portion of the original Kansas Interstate system built at the time, the 2.2-mile long viaducts between Kellogg Avenue and 21st Street North. The northbound bridge is 12,111 feet long while the southbound span totals 12,497 feet.2 Technical issues extended work on the Canal Route to a December 1979 completion date.1

Interstate 35W utilized the preexisting Newton bypass and was complete in the Salina vicinity by 1965. The Newton bypass was constructed in the 1950s initially as a connector from U.S. 81 on Kansas Avenue to U.S. 50 at the current wye interchange (Exit 33) with I-135.
The north end of Interstate 135 consisted of a trumpet interchange with I-70 until construction of the U.S. 81 freeway to Minneapolis – 1967 Kansas Official Highway Map
The Canal Route in Wichita was the last section of Interstate 135 opened to traffic – 1977 Kansas Official Highway Map

As approved by AASHTO on July 13, 1976, Interstate 35W was renumbered as Interstate 135 on September 13, 1976. There are two remaining I-35W’s nationally, one at Fort Worth, Texas and the other through Minneapolis, Minnesota.

Funded by the American Recovery and Reinvestment Act (ARRA) in 2009, a $16.1 million project reconfigured the full cloverleaf interchange joining Interstate 135 with 47th Street (U.S. 81 to the west) in south Wichita. The two-year project was unveiled on August 28, 2009 with construction commencing on September 8, 2009. It coincided with development of the South Fork retail and hotel complex at the southwest corner of the exchange. Project elements included the rebuilding of four bridges for 47th Street South, over both I-135 and adjacent Big Slough Creek, and the removal of three ramps with the installation of three signalized intersections.3

A new diamond interchange is under construction along Interstate 135 & U.S. 81 at Mohawk Road to the north of McPherson. The $7.018 million project links separate segments of Mohawk Road to serve an industrial park and provide additional access to the north side of McPherson. The bid for the project was let on October 21, 2015. Scheduled work ran through May 26, 2017,4 and a ribbon cutting ceremony took place for the new ramps on April 4.6

Pull through signage for I-135 omits Wichita presently. Photo taken by Michael Summa (1986).

The former alignment through Wichita followed Broadway. Photo taken by Ben Prusia (03/02).

Perspective from Interstate 35 (Kansas Turnpike) north
Replaced by 2015, the one mile sign for Exit 42 and Interstate 135 north appears at the 63rd Street South underpass along the Kansas Turnpike north. Sign specifications for Exit 42 include both I-235 and U.S. 81 for the adjacent exits of I-135, similar to practices found on the Pennsylvania Turnpike, where nearby routes are included as if they were served directly by the toll road. Photo taken 10/20/03.
