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. Its northern terminus is at an interchange with I-135/U.S. Highway 81 (US-81)/K-15/K-96/K-254 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 I-35 (here known as the Kansas Turnpike) at I-135's own southern terminus.
