Illinois → Pennsylvania · Interstate 90 / Interstate 94
On heavy-rain or dense-fog days the Chicago, Illinois, to Pittsburgh, Pennsylvania, leg routinely demands well more than the 7h 24m 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 777 km (483 miles) over varied topography between Chicago (the largest Midwest metropolis and a national logistics hub) and Pittsburgh (the historic Steel City at the confluence of the Allegheny and Monongahela rivers), 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 $64.95 for the 70.6 liters (18.7 gallons) consumed. Even in adverse conditions, the flat tariff of $0.43/km guarantees the standard outbound payout of $334.11 — log any incidental costs (extra toll, mandatory meal, emergency lodging) in a separate field on the Clara receipt.
