Texas → Tennessee · Interstate 30 / Interstate 35W
On heavy-rain or dense-fog days the Fort Worth, Texas, to Memphis, Tennessee, leg routinely demands well more than the 8h 25m estimated: Interstate 30 / Interstate 35W carries known hydroplaning hot spots and reduced-visibility corridors that justify dropping to 35 mph through a few short stretches. The outbound run covers 779 km (484 miles) over varied topography between Fort Worth (the fifth-largest city in Texas and historic livestock-trading center known as Cowtown) and Memphis (the Mississippi River blues capital and the global FedEx superhub), 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 $65.14 for the 70.8 liters (18.7 gallons) consumed. Even in adverse conditions, the flat tariff of $0.43/km guarantees the standard outbound payout of $334.97 — log any incidental costs (extra toll, mandatory meal, emergency lodging) in a separate field on the Clara receipt.
