For those not familiar with the route of the Lincoln Highway, I now have a map available based on the one in my Greetings book. Click the thumbnail below or the really tiny one to the right and you’ll get a US map up to 19 inches wide, just like this one:
The first generation represents the “Proclamation Route” of 1913. Towns like Trenton, NJ; Marion, OH; and Ogden, UT were quickly removed (though Ogden would later be put back on).
You’ll also see the Colorado Loop, which the LHA soon regretted but nonetheless approved of for two years. Note also that there were two ways around Lake Tahoe in eastern California. West of Sacramento, the 1928 rerouting is being debated of late as to whether the change was officially endorsed by the LHA board. It’s included because that’s where the LHA’s concrete posts went in 1928.
The first tally of the Lincoln Highway’s length was 3,389 miles (including Camden and Marion but not Ogden), though it would always be in flux due to bypasses and realignments. More than a decade later, the now more-famous US Route 66 would run 2,448 miles from Chicago to Los Angeles (though it likewise would vary in length).
