K-89 is a spur route that serves the city of
Halstead in central
Harvey County. The road continues south as Main Street, which contains a variety of
historic sites, including its
post office,
museum and former railroad station, a pair of
historic homes, and the
Bernhard Warkentin Homestead, which is a
National Historic Landmark. K-89 heads north by Riverside Park—the site of the Old Settlers Picnic and of filming for the 1955 movie
Picnic—along Hertzler Memorial Highway, which honors "Horse and Buggy Doctor"
Arthur E. Hertzler. The highway passes through an S-curve to veer east onto a section line road, which the highway follows to its end at
US-50 between
Burrton and
Newton. The roadway that was to become K-89 was originally planned as K-59. The Kansas State Highway Commission approved a purchase order for right of way to construct K-89 on September 13, 1932. The highway was built in the second half of 1934 as an improved
dirt road that was partially funded by
national recovery grants. However, before the state had paved the highway, the commission decided to eliminate several sharp curves in the highway's planned course and return the unused land to the former property owners in a November 15, 1935, resolution. K-89 was paved on its present course by 1936. ==K-90==
