However, for the purposes of preparing plans and specifications, acquisition of right-of-way, the performance of all things necessary to the commencement of a construction or improvement project on a part or all of such a route by the county and the use of county highway or motor fuel tax funds therefor, such route shall be treated and considered as though it were then a part of the county highway system.\nUpon the commencement by the county of a construction or improvement project on a part or all of a route so designated as such a municipal extension, the part so to be constructed or improved shall thereupon become a part of the county highway system.","path":["CHAPTER 605 ROADS AND BRIDGES","Illinois Highway Code."],"source_url":"https://www.ilga.gov/legislation/ILCS/details?ActID=1745\u0026ChapterID=45\u0026ChapAct=FullText\u0026Print=True","current_through":"at least Public Act 104-790","vintage":"","retrieved_at":"2026-09-15T04:46:39Z","sha256":"21bac4700a2ff94a0359618a1c318acf06876e2d4790e7612e3a85b8b467459d","source_id":"us-il","stale":false,"prev":"us-il/605-ilcs-5-5-105","next":"us-il/605-ilcs-5-5-107"},"notice":"GroundRules: Original legal text.
