I-10 Going through Phoenix to the California border in the USA, by the Interstate 10, is a pretty hairy adventure. Located in Arizona, United States, the I-10 is 89 miles (143km) of dead straight road outside Phoenix. Only in 2010 this portion of the highway saw up to 85 deaths. The road, with two slight corners over 80 miles, links Buckeye (in Maricopa County) and Brenda (in La Paz County). It’s a straight road running right through the desert for 1 h 14 min. It was built in 1990 and the surface is asphalted. You’re driving through a desert, so apart from the odd cactus or abandoned tumble-weed town you’re not going to see many people or petrol stations by the roadside.
