New York → Pennsylvania · Interstate 90 (New York State Thruway)
On heavy-rain or dense-fog days the Buffalo, New York, to Philadelphia, Pennsylvania, leg routinely demands well more than the 5h 3m estimated: Interstate 90 (New York State Thruway) carries known hydroplaning hot spots and reduced-visibility corridors that justify dropping to 35 mph through a few short stretches. The outbound run covers 531 km (330 miles) over varied topography between Buffalo (the western New York gateway to the Niagara Frontier and Lake Erie) and Philadelphia (the birthplace of American independence and sixth-largest US city), 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 $44.44 for the 48.3 liters (12.8 gallons) consumed. Even in adverse conditions, the flat tariff of $0.43/km guarantees the standard outbound payout of $228.33 — log any incidental costs (extra toll, mandatory meal, emergency lodging) in a separate field on the Clara receipt.
