Interstate 235 (abbreviated I-235) in Kansas is a 16.52 mile-long north–south bypass spur route of Interstate 35 that travels through the western part of Wichita. Its northern terminus is at an interchange with K-96 and Interstate 135/U.S. Route 81 north of the city, where the freeway continues east as K-254. The southern is at I-135/US-81 shortly before US-81 separates from I-135 and I-135 connects to Interstate 35 (here known as the Kansas Turnpike) at I-135's own southern terminus.
Aside from the Kansas Turnpike, I-235 is the first component of the Interstate system to be built in Wichita. The vast majority of its length, running from its original southern terminus at the Kansas Turnpike to the Broadway Ave. interchange in north Wichita, was built in 1960-61 and was open to traffic by 1962. The remaining unbuilt length, connecting Broadway Ave. to the northern terminus, was open to traffic by July 1965. The short length of I-235 between the Turnpike interchange and the present I-135/I-235 split later became part of I-135.
