The General Assembly, constituting the Legislature of the State of Illinois, assents to the provisions, terms, conditions and purposes of the Federal Aid Road Act as defined in this Code. In the location of highways which will be part of the National System of Interstate and Defense Highways referred to in the Federal Aid Highway Act of 1956 (public law 627 of the 84th Congress), existing highways of the State highway system as defined in this Code shall be used to the extent as the Department finds such use is practicable, suitable and feasible. The selection of such locations shall be made as provided in Section 3-103 of this Code. (Source: Laws 1959, p. 196.)

(605 ILCS 5/3-102) (from Ch. 121, par. 3-102) Sec. 3-102. In accordance with the provisions of such Federal Aid Road Act, as soon as the State has made provision for the completion and maintenance of 90% of the network or primary or interstate and secondary or intercounty federal aid highways equal to 7% of the total public highway mileage of the State specified in the Federal Aid Road Act, the Department may, with the approval of the designated authority of the United States Government, increase the mileage of such primary or interstate and secondary or intercounty network by additional mileage equal to not more than 1% of the total public highway mileage of the State, and thereafter may make like increases in the mileage of such network whenever provision has been made for the completion and maintenance of 90% of the mileage of such network previously authorized in accordance herewith, and may construct and improve highways so selected in accordance with this Code and any other laws applicable, as moneys are appropriated for this purpose and made available by Acts of Congress and Acts of this State. When selecting highways to be added to such network by and with the approval of the designated authority of the United States Government, as heretofore provided, the Department shall, so far as is practicable and consistent with the Acts of Congress, distribute in the several counties the mileage proposed to be added, and, as nearly as may be, so as to provide simultaneously for additional highways in the different sections of this State. When designating the projects on such network of highways which are to be improved with the current allotments of federal funds made available by Acts of Congress and with funds made available by Acts of this State to be used with such federal funds, the Department shall distribute such federal aid projects equitably and fairly among the different sections of the State and, so far as is practicable and consistent with Acts of Congress, among the several counties.

In locating and constructing a highway which will be a part of the National System of Interstate and Defense Highways local needs, to the extent practicable, suitable and feasible, shall be given equal consideration with the needs of interstate commerce, so that such highway will not unduly discommode or interfere with local traffic or will not destroy reasonable access to schools, churches, markets, trade or community centers.

The highways included in such network shall be selected and designated in accordance with the provisions of the Federal Aid Road Act, and shall consist of highways not included in the federal aid primary or federal aid urban networks.

The local highway authorities having jurisdiction over a highway or street prior to its selection and designation as a part of the federal aid secondary network shall continue to be responsible for its maintenance until such time as it has been constructed as provided herein. After a highway has been so constructed, the Department is authorized to maintain it, or, with the approval of the Federal Highway Administration, to enter into a formal agreement with the appropriate officials of the county in which such highway is located, either prior to or after construction, for its maintenance at the expense of such county. If at any time the Department finds that the highway is not being properly maintained by such county, the Department shall call such fact to the attention of the county and if within 90 days after receipt of such notice the highway has not been put in a condition of maintenance satisfactory to the Department and the Federal Highway Administration, then the Department, with the consent of the Federal Highway Administration, shall withhold approval of any further federal aid secondary projects in such county until such highway has been so restored.
