Is Route 66 still drivable?

A large portion of Route 66 remains paved and drivable (approximately 85%) with a standard saloon car, although with an off-road vehicle this could be higher. There are some variations in the Route as the original alignment underwent some changes in the early years to improve the road and make it safer, so occasionally travellers may find themselves presented with choices between a paved section or a more rugged “dirt” section.
