310.29  Maintenance by county.
  Any farm-to-market road constructed under this chapter shall be maintained by the county. If any county fails to satisfactorily maintain any road that is part of the federal aid secondary system, the department shall give the board of supervisors notice of that fact. If within sixty days after receipt of notice the highway has not been placed in proper condition of maintenance the department may withhold authorization for letting of any project using farm-to-market funds until a proper condition of maintenance has been restored.
