Interstate 235 (I-235) in Kansas is a 16.52-mile-long (26.59 km) north–south bypass spur route of I-35 that travels through the western part of Wichita.

Aside from the Kansas Turnpike, I-235 is the first component of the Interstate Highway 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 Avenue interchange in north Wichita, was built in 1960–1961 and was open to traffic by 1962.

[4] The remaining unbuilt length, connecting Broadway Avenue 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.
