(3) The maximum inspection interval specified

interim inspections available for review by the department and federal
authorities. If the maintaining authority has failed to perform the inspection,
the county highway commissioner in the county in which the bridge is located
shall perform the interim inspections as directed by the department and keep a
record of the interim inspections available for review by the department and
federal authorities. Upon receipt of the department's notice and direction, the
county shall perform the interim inspections or cause them to be performed.
