At W. Kanesville Boulevard, which carried US 6, the one-way couplet ended and Iowa 192 turned west onto Kanesville. Shortly thereafter, the street turned into Broadway. US 6 and Iowa 192 headed west together along W. Broadway on a viaduct over a line of the Union Pacific Railroad. One block after the viaduct returned to street level, Iowa 192 left US 6. It traveled north through a residential area along N. 16th Street. Shortly after crossing a Canadian National Railway line, the road became a divided highway. Iowa 192 ended as it merged into I-29 traffic close to the northern city limits of Council Bluffs. There was no direct access to southbound I-29 from northbound Iowa 192. Likewise, northbound I-29 traffic could not directly access southbound Iowa 192.
