605 ILCS 5/6-326.1
Existing township and district roads may be temporarily closed and reconstructed by the filing with the highway commissioner of the district involved and with the County Superintendent of Highways of a petition signed by all of the owners of the property contiguous to both sides of that portion of the roadway to be temporarily closed and reconstructed by the petitioners. A copy of this petition shall be published in at least one newspaper published in the township or district or, in the absence of such published newspaper, in at least one newspaper of general circulation in the township or district or, in the absence of such generally circulated newspaper, by posting copies of the petition in 5 of the most public places in the district in the vicinity of the road to be temporarily closed and reconstructed. The Road Commissioner shall provide for publication or posting at least 10 days prior to any decision on the matter. If the commissioner is of the opinion that the temporary closing of the road is in the public and economic interest and that the temporary closing will not materially interfere with the flow of traffic on the township and county road system then, upon the approval of plans for the reconstruction of the road by the District Commissioner and the County Superintendent of Highways and the depositing with the commissioner of a contract and corporate surety bond approved by the Highway Commissioner and the County Superintendent of Highways properly guaranteeing the replacement of the road in as good or better condition as existed prior to the closing, the commissioner may temporarily close the road for a period not to exceed 3 years.
