Does Highway 1 run from Canada to Brazil

You may be talking about US 81 (the Pan American Highway) which runs
from Canada near Fargo, ND and through Waco, TX. The original intent
was to connect clear to the tip of SA, and with the exception of the
Darien Gap (earlier posts) I think is complete. The last portion of
the US portion of the US link to be completed was the Meridian
Bridge at Yankton, SD, a few miles from my home.

No section of the Pan-American Highway has been officially designated in the
U.S. or Canada, though sections have been named locally (like I-25 in
Albuquerque and I-35 in San Antonio). From what I can find, the following
points on the Mexican-U.S. border are termini of the PAH:
Laredo - original terminus via 85 to Mexico City
Nogales - via 15 to Mexico City
El Paso - via 45 to Mexico City
Eagle Pass - possibly via 57 to Mexico City
Pharr - via 40 to Monterrey
Brownsville - via 101 to Ciudad Victoria

Tourism agencies often designate certain routes north of Mexico as the PAH
to provide a route for tourists to drive.
