Interstate 135 (I-135) is an approximately 95.7-mile-long (154.0 km)auxiliary Interstate Highway in central and south-centralKansas,United States. I-135, which is signed as north–south, runs betweenI-35 and theKansas Turnpike inWichita north toI-70,U.S. Highway 40 (US-40), andUS-81 inSalina. Except for the first 0.46 miles (0.74 km), I-135 overlaps US-81 its entire length. The route also runs through the cities ofMcPherson,Newton, andPark City.

The highway was designated asInterstate 35W (I-35W) until September 1976, when it was renumbered as I-135 to conform to newAASHTO policies that eliminated most suffixed Interstate Highways. It is currently the longest three-digit spur with an odd first digit in the Interstate System.

I-135 begins from the south at exit 42 on theKansas Turnpike. (The exit is signed as I-135/I-235/US-81 for Wichita and Salina.)US-81 joins I-135 0.5 miles (0.80 km) later at exit 1A (East 47th Street South) and remains concurrent with it for the rest of its length. Less than one mile (1.6 km) from the Kansas Turnpike tollbooth,I-235, a loop around the westside of Wichita, branches off the highway at exit 1C. I-135 continues northward from there, running just east of the Wichita downtown area. It reunites with I-235 at exits 11A and 11B at milepost 11 at the loop's other end.

I-135 leaves Wichita and continues northward toNewton where it turns northwest around milemarker 33. The freeway continues in this direction for 20 miles (32 km), returning to a due north course atMcPherson.

The stretch of I-135 inSaline County from the Saline–McPherson county line to the highway's terminus atI-70, is designated as theBen E. Vidricksen Highway, in honor of a state senator who was active in pushing for the highway's enlargement.^[1][2]

The route ends on the northwest side ofSalina, at its intersection at I-70. The road continues as US-81 north of this interchange.

Interstate 35W
Existed	1971[3]–September 13, 1976[4]

Construction on the Canal Route portion of I-135 (in Wichita, where the Chisholm Creek Canal runs through the median of the highway) was begun in 1971.^[3] This portion of the route took eight years to complete with a cost of $32 million (equivalent to $111 million in 2024^[5]).^[3] It was built through the middle of the city'sAfrican-American neighborhood, known asMcAdams.^[6]

Until September 13, 1976, I-135 was signed asInterstate 35W (I-35W). The Interstate's full length was completed in December 1979.^[4]

In 2021, work began to rebuild the northern junction with I-235 in Wichita.^[7] A two-laneflyover ramp connecting northbound I-135 to southbound I-235 which replaced the previous one-lane loop ramp opened on May 31, 2023.^[8]
