I-74 Road Conditions & Weather

I-74 runs 700 miles west to east. The table below covers the 546 miles of it our own route maps hold, across 5 states. Its longest stretch is 220 miles across Illinois; its shortest is 5 miles in Iowa.

Mile markers count from each state's western line and start again at the next one, which is how most states number their exits as well. They are measured along the same road geometry these pages draw, so they land within a mile or two of the posted markers. A toll road that runs its own continuous numbering is the exception — on the New York Thruway the posts continue from New York City — and there the figure is how far into the state the place is rather than the number on the sign. Distances are measured state by state, never across a gap. Iowa and Ohio carry too little of the road for a page of their own — under the 25 miles that separate two markers on the map above — so they are named without a link.

Winter reporting is off for the season. The state DOT feeds this page reads for Iowa and Illinois run from October 15 to April 15; outside that window they change only as needed. Our own forecast below runs year-round.

Reports for Iowa and Illinois come from each state's DOT, entered by maintenance staff and describing what is on the pavement, not the forecast; the state pages carry each DOT's terms and notices. No DOT winter report is read here yet for Indiana, Ohio and North Carolina. Always check with the responsible state DOT before setting off.
