The Illinois Department of Transportation has announced the release of the new Illinois Official Highway Map. The map includes route updates, detailed sections devoted to cities from Zion and Cairo as well as a feature that shows mileage between towns. The new map’s cover features a brick section of Old Route 66 between Auburn and Chatham. The map is paid for with funds from the Federal Highway Administration and published by IDOT every two years on recycled paper with soybean oil-based inks.
