North Carolina → North Carolina · Interstate 85 / Interstate 77
On heavy-rain or dense-fog days the Charlotte, North Carolina, to Raleigh, North Carolina, leg routinely demands well more than the 2h 21m estimated: Interstate 85 / Interstate 77 carries known hydroplaning hot spots and reduced-visibility corridors that justify dropping to 35 mph through a few short stretches. The outbound run covers 246 km (153 miles) over varied topography between Charlotte (the Queen City of the Carolinas and the second-largest US banking center) and Raleigh (the capital of North Carolina and anchor of the Research Triangle), 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 $20.61 for the 22.4 liters (5.9 gallons) consumed. Even in adverse conditions, the flat tariff of $0.43/km guarantees the standard outbound payout of $105.78 — log any incidental costs (extra toll, mandatory meal, emergency lodging) in a separate field on the Clara receipt.
