Driving from San Antonio to Anchorage: Not Possible by Road

You cannot drive from San Antonio, Texas to Anchorage, Alaska. No road connects the continental U.S. to Alaska through Canada without a ferry or passing through Canada (which requires passports and is a drive of ~4,500 miles via the Alaska Highway). The Alaska Highway (Dawson Creek, BC → Delta Junction, AK) is the only land route, but it starts in Canada. A pure U.S.-only road does not exist.

Options: Fly (6–8 hrs), ship vehicle + fly, or drive through Canada (requires passport, insurance, ~45 hrs driving).
