US Route 6 was deemed "Grand Army of the Republic Highway" in 1953. Forgotten for so long, there seems to be new interest in its designation, as reported in THIS Desert News Utah article.
US Route 6 is the longest contiguous transcontinental route in the USA. Running from Provincetown, MA to Bishop, CA (and before 1964 to Long Beach, CA), Route 6 goes through 14 states. This is your guide along all of its original 3,652 miles. From Revolutionary War sites to pioneer settlements and western mining towns, Route 6 offers an in-depth lesson in US History, charms of yesteryear and comforts of modern times.
