605 ILCS 5/6-901
Annually, the General Assembly shall appropriate to the Department of Transportation from the Road Fund , the General Revenue Fund, or any other State funds, or a combination of those funds, $60,000,000 for apportionment to counties for the use of road districts for the construction of bridges 20 feet or more in length, as provided in Sections 6-902 through 6-907 .
The Department of Transportation shall apportion among the several counties of this State for the use of road districts the amounts appropriated under this Section. The amount apportioned to a county shall be in the proportion which the total mileage of township or district roads in the county bears to the total mileage of all township and district roads in the State. Each county shall allocate to the several road districts in the county the funds so apportioned to the county. The allocation to road districts shall be made in the same manner and be subject to the same conditions and qualifications as are provided by Section 8 of the Motor Fuel Tax Law with respect to the allocation to road districts of the amount allotted from the Motor Fuel Tax Fund for apportionment to counties for the use of road districts, but no allocation shall be made to any road district that has not levied taxes for road and bridge purposes in such a manner that is eligible for allotment of Motor Fuel Tax funding pursuant to Section 8 of the Motor Fuel Tax Law. "Road district" and "township or district road" have the meanings ascribed to those terms in this Act.
Road districts in counties in which a property tax extension limitation is imposed under the Property Tax Extension Limitation Law that are made ineligible for receipt of this appropriation due to the imposition of a property tax extension limitation may become eligible if, at the time the property tax extension limitation was imposed, the road district was levying at the required rate and continues to levy the maximum allowable amount after the imposition of the property tax extension limitation. The road district also becomes eligible if it levies at or above the rate required for eligibility by Section 8 of the Motor Fuel Tax Law.
The amounts apportioned under this Section for allocation to road districts may be used only for bridge construction as provided in this Division. So much of those amounts as are not obligated under Sections 6-902 through 6-904 and for which local funds have not been committed under Section 6-905 within 48 months of the date when such apportionment is made lapses and shall not be paid to the county treasurer for distribution to road districts.
