March 22, 2003: North end of IA 107 at the Clear Lake city limits. This used to be where it intersected IA 106. The number, continuously in use since the second half of 1920, was decommissioned in 2003 — except where it wasn’t.
Since Cerro Gordo County’s 2003 agreement was done separately from the Second Great Decommissioning, the segments inside Meservey and Thornton (above) were still on the state rolls for nearly another decade. The county was in charge of maintenance and presumably plowing, though. The last vestige of IA 107 officially was extinguished June 30, 2011.
