Although it no longer exists as a true highway, Historic Route 66 gets designated in many sections of the 2,448 miles from Santa Monica CA to Chicago IL... We picked up the route in Gallup NM and headed east to Albuquerque where some of the highway was replaced by I-40. A lot of politics and negotiation starring with Route 66 creation in the 1930's until it's decommissioning in the 80's and now it's revival as Historic Route 66!
