What’s the longest Federal Highway in the USA? US Route 20. What’s the SECOND longest (and longest CONTIGUOUS) highway? US 6!
US Route 6 History
The historic highway, also known as the Grand Army of the Republic Highway, is now 3,205 miles long.
Before 1964, when California renumbered its roads, and Route 6 ran coast to coast from Provincetown, Massachusetts, to Long Beach, California, Route 6 was the longest highway in the land – at 3,652 miles.
Now, driving US Route 6 will bring you through 14 states and some of the best small towns and cities in America that, before establishing the Interstate Highway system, had their moments in the sun.
U.S. Route 6 Terminus
Historic Route 6 begins and ends in flamboyant, artsy, touristy, entertainment-rich Oceanside towns. Provincetown, MA, in Cape Cod, on the Atlantic Ocean, draws playwrights, gay activists, and many tourists every summer.
Long Beach, CA, on the Pacific Ocean, an outer borough of Los Angeles, is rich in the glitz of a similar sort.
What To Expect On US 6
What’s in between is a virtual timeline of American history. Revolutionary War sites in New England give way to pioneer homes in the plains and prairies of Iowa and Nebraska. And then eventually to the stark silver and gold mining camps in Colorado, Utah, Nevada, and California.
On its way across the United States, Route 6 travels through two towns called Brooklyn, and neither is in New York.
It touches two oceans, runs along the shore of one Great Lake (Erie), crosses most of the country’s major rivers, traverses five state capitals, and climbs, exhilaratingly, up and over the Continental Divide.
It meanders through land both barren and lush.
US 6 takes you from the Technicolor gardens and forests of the East Coast to the sepia tones of the Western desert through some of the friendliest cities and towns in our country’s midsection.
Most are not tourist destinations. You’d likely never know about them except that they are on what was once the main cross-country route.
But for road-trippers, that’s part of the joy of discovery. In many of these locales, inhabitants welcome strangers with open arms, introducing travelers to the best places where they eat and shop.
Plan Six Weeks On US Route 6
To do the whole route justice, plan to spend at least six weeks on the road. Of course, you might be tempted to idle in resort areas and larger cities, which will extend your trip.
If you’re in a rush (besides the point of a two-lane highway trip), you can drive in half the time by picking and choosing what is most important to you.
You can also break up the journey into the following segments (designed to begin and end in cities with accessible airports).
