CARxR 1.08: Highway Numbering: U.S. Highways (Part I)CARxR 1.08: Highway Numbering: U.S. Highways (Part I)

In this episode, we continue our exploration of numbering of state highways by turning our attention to the U.S. highway system. These are the white shields with black numbers. It is the second episode in a four part miniseries on highway numbers in California. In this episode we talk about the history of the US highway system, how the US highways are numbered, how things have changed in the post-Interstate era, and we wax rhapsodic on the nostalgia of US highways. The remaining episodes in the miniseries will explore the numbering of and the history of California’s Interstates, and the signed county route system.

Our interview for this episode was to be with Jim McDonnell of AASHTO on AASHTO’s role in assigning US and Interstate numbers. But we’ve run into scheduling difficulties and haven’t been able to coordinate a recording time by our scheduled drop date. So consider this Part I of the episode. When we can get things coordinated with Jim we’ll record and release Part II.
