K-254 links Wichita to El Dorado. The road begins at the intersection of I-135/US-81/K-15 and I-235 north of Wichita. It bypasses Kechi, Benton and Towanda, ending in downtown El Dorado at an intersection with US-54 and US-77. It is limited access from I-135 to just east of Kechi. It is then four-lane divided with at grade intersections to El Dorado with the exception of a diamond interchange at K-196. There is a stoplight interchange with I-35/Kansas Turnpike on the west side of El Dorado. It derives its number from US-54.

The state is studying a northwestern bypass of Wichita, which would be US-54. If that happens KDOT would designate K-254 as US-54.
