Illinois → Indiana · Interstate 90 / Interstate 94
On heavy-rain or dense-fog days the Chicago, Illinois, to Indianapolis, Indiana, leg routinely demands well more than the 2h 59m estimated: Interstate 90 / Interstate 94 carries known hydroplaning hot spots and reduced-visibility corridors that justify dropping to 35 mph through a few short stretches. The outbound run covers 313 km (194 miles) over varied topography between Chicago (the largest Midwest metropolis and a national logistics hub) and Indianapolis (the capital of Indiana and home of the Indianapolis 500 motor race), demanding sharper attention on mountain descents and shoulder-less curves. Before pulling out, check brake-pad wear, tire tread depth, and washer-fluid level in the reservoir. Fuel spend holds near $26.22 for the 28.5 liters (7.5 gallons) consumed. Even in adverse conditions, the flat tariff of $0.43/km guarantees the standard outbound payout of $134.59 — log any incidental costs (extra toll, mandatory meal, emergency lodging) in a separate field on the Clara receipt.
