Rock Island County also places a restrictive vehicle weight limit on the County Highway 77 (Z), Niabi Zoo Road in the spring when the frozen ground under the roads begins to soften. Although the time the postings are put into effect varies based on depth of frozen ground and air temperatures, the common period of the "spring posting" is mid-February to mid-May and over weight or over width permits will not be issued during the days when posted.
