The freeway resumes as the road crosses the city limits of Wichita near Wichita Dwight D. Eisenhower National Airport. In Wichita, US 54/US 400 is known as Kellogg Avenue, and has junctions with I-235, I-135 and I-35, the Kansas Turnpike, before a junction with K-96. The Kellogg Avenue freeway has six lanes and extends from 111th Street on the west side of Wichita to Zelta just after the I-35/Kansas Turnpike interchange on the east side. Upgrading of Kellogg Avenue from a surface arterial to a freeway has been underway since the mid-1980s, with the latest interchange project opening in late 2019. The road gets its name from Milo Bailey Kellogg, a shopkeeper and Civil War veteran who was the city's first civilian postmaster in 1870.
