Claim to fame: after part of US 6 was decommissioned in 1964, US 20 became the longest US route, and in fact remains the longest highway of any classification in the U.S.
Since the US routes were first commissioned, the east terminus of US 20 has always been in Boston, although its exact endpoint has changed over the years. US 20 comes into town on Brighton Avenue, which then becomes Commonwealth Avenue. Formerly this was the last eastbound marker...

...but in 2012 or 2013 it appears MassDoT re-signposted the routes in this part of town, and now the easternmost segment of US 20 has shields that are more MUTCD-compliant. As of 2014, the last eastbound marker was just past the BU Bridge:

Signage approaching Kenmore Square indicates the route at which US 20 terminates:

MA hwy. 2 approaches Commonwealth from the right, via Beacon Street. Here, where those two roads intersect, MA 2 switches over to Commonwealth, and the US 20 designation ends. For years there was a sign assembly attesting to that fact, but when that traffic island was altered in about 2008, the "End" sign was removed and not replaced until 2017:

The US 20 designation formerly extended further ahead from there. Originally, US 20 continued ahead via Beacon and ended at the State House:

That interactive image is looking north on Park Street; US 20 originally began to the left on Beacon. Sometime in the 1930s, part of Beacon became one-way westbound, so US 20 was moved to the end of Commonwealth Avenue at the Public Garden:
c. 1956, Gousha

|
Today Commonwealth heading west from there is designated MA 2. But as one approaches the intersection with Beacon, signs note that the junction with US 20 is upcoming...

...and in December 2016 a new sign was installed on westbound Commonwealth, just before the beginning of US 20...

...but unfortunately the mileage on that sign is not quite correct. MassDoT copied the information from a similar sign that was posted at the route's western terminus in Oregon (more details below, in the Newport section).

Just ahead, where Commonwealth and Beacon traffic diverge, US 20 begins at Kenmore Square:

From 1926 to 1940, the west end of US 20 was at the east entrance to Yellowstone National Park. It could be argued that the west end of the eastern segment of US 20 is still at the east entrance to Yellowstone: this line of reasoning holds that the "US highway 20" which was commissioned in 1940 (running from the west entrance of Yellowstone to Oregon) is a separate (western) segment of that route. While that is technically true (since US routes are not signed in Yellowstone), another line of thought considers US 20 to be a single route which was extended west via an implied route through the Park.

Some historic maps suggest that when US 20 was first extended west, it ended in Albany OR for a year or two:

c. 1941, ODoT
|

Note how US 20 is shown running through Lebanon to Albany, but the road between Albany and Corvallis is marked as SR 26, as is today's US 20 from Corvallis towards Newport. This photo was taken looking north on Main Street:

Originally US 99E followed the route of the minivan and the pickup visible in the distance: it came in from the right on Salem Avenue, then ahead on Main a block or two, then left on either 1st or 2nd Avenue. Westbound US 20 came in from the right via Santiam Highway (the road in the foreground), then would have gone ahead one block on Main, ending at the next intersection (Salem), at its junction with US 99E (that intersection has now been reconfigured into a roundabout).
|
But that endpoint was very short-lived: in the early 1940s, US 20 was extended past Albany, through Corvallis and on to its current western terminus at Newport. In this photo, we are looking west on Olive Street (US 20):

The US 20 designation ends just ahead; this photo shows the intersection:

The traffic signal is at the Coast Highway, or US 101; the Pacific Ocean is about a half-mile straight ahead. The green sign directs Waldport and Florence traffic to the left, while Depoe Bay and Lincoln City is to the right. Underneath that is a blue sign denoting that US 101 is also the Pacific Coast Byway scenic route. When that sign was installed, it unfortunately replaced an "End US 20" assembly.

Here, the cars in the foreground are at the west end of US 20, as we look north on US 101...

The "Begin" signs were tacked on about a week before that photo was taken. "Begin" signs are not common anywhere in the country, and these may be the only ones in Oregon. In late 2016, an even better improvement was made: drivers taking that turn to the east were treated to a really cool new sign:

US Ends .com supports posting information like that at the endpoints of cross-country routes. However, the "3365 miles" figure is unfortunately incorrect. By our calculations US 20 (as routed in 2016) is more like 3295 miles, so the information on that sign is overstated by about 70 miles. (It should be noted that both of those figures include an 80-mile implied route through Yellowstone National Park, where US 20 is not signed and technically does not exist.)

The source of the error on the sign comes from the 1989 AASHTO route log. Not only were there probable errors made in their calculations, but also, during the intervening 27 years, some segments of US 20 have been rerouted. Apparently ODoT just assumed AASHTO's figure was still correct, and then MassDoT assumed that ODoT's figure was correct. Nevertheless, the idea behind these twin signs is a good one.
Formerly the first standard confirming assembly was about six blocks further ahead: |
