From an official standpoint Route 99 fits into the same category as Route 66: it does not exist anymore.  Historically US 99 was one of the country's main north-south highways, serving several of the major cities in California, Oregon, and Washington.  ​This map showing the original extent of US 99 was included in a 1928 US Dept. of Agriculture Office of Information press release, issued shortly after the US routes were commissioned:
Picture
c. 1927, US Government Printing Office
As was often the case with major US routes, a parallel interstate was later built through the same corridor.  Many segments of Interstate 5 were created by expanding the existing US 99 into an interstate-quality road.  In most other areas, I-5 ran right alongside US 99, or at least roughly paralleled it.  By the mid-1960s, US 99 was obsolete, and its route was stripped of the US highway designation.

Morrison, Feb. 2019
But Route 99 is also similar to US 66 in this way: today, the road segments that historically carried US 99 traffic are enjoying a rather significant revival.  In fact, public awareness of old 99 may well be second only to Route 66 (see Historic Highway 99 Association). 

For the first few years the south end of US 99 was at its junction with US 80 in El Centro:
Picture
c. 1927, Rand McNally
This photo was looking north on Imperial Avenue.  The cross street is Adams Avenue, designated today as county road S-80, which is the modern equivalent of old US 80:
Picture
Karners, Dec. 2011
However, US 80 traffic may not have used Adams to the east (right). Instead, westbound US 80 may have come in from the right on Main Street (a couple blocks behind the camera), then north on Imperial to this point, and then continued via Adams to the left.  US 99 followed what is now CA hwy. 86, so either way it probably would have begun straight ahead.  

​It was not long before the south end of US 99 was extended to the international border at Calexico:
Picture
c. 1939, Rand McNally
US 99 essentially followed what is now CA hwy. 111 southward into Calexico... but just shy of the modern border crossing, US 99 went east on 3rd Street.  That is no longer permitted, so the Historic US 99 signage shown here has been posted on 2nd for several years now:

Friedman, May 2020

Ballard, Mar. 2021
The placement of that particular "End" assembly is a bit odd (as there are another two "Historic 99" signs ahead on 2nd), but it was decided that the "End" assembly should be placed in a highly-visible location.  US 99 actually continued ahead another three blocks, and upon reaching Heffernan Avenue, traffic was directed south for two more blocks, ending at the historic border crossing:
Picture
Karners, Dec. 2011
Not much to look at today, as that crossing has since been closed in favor of the modern port of entry, just to the west (right).  But some great historical images have been digitized; these first ones were taken looking that same direction.  Not only was there a trailblazer posted within one block of the US 99's endpoint...
Picture
c. 1950, Los Angeles Times (linked to source)
...but just a little further ahead was an "End" sign:

c. late 1940s, Michael Semas Collection
Facing the opposite direction (north on Heffernan), this was a view of the south beginning of US 99:

c. 1950, Los Angeles Times (linked to source)
On the right side of that photo, two US 99 shields are visible, enlarged here:

That second one was located just past 1st Street, in the same place where the retro "Begin" assembly is posted today:

That was heading north on Heffernan from the old crossing.  Nice signs, but unfortunately there were no further signs directing US 99 pilgrims (probably because 2nd is now one-way eastbound).  ​In 1963, the south end of US 99 was temporarily truncated to Los Angeles, because I-10 had been completed east of there, and south of Indio US 99 was redesignated as CA 86.  

Starting in 1926 and for more than 40 years, the north end of US 99 was at the Canada border in Blaine:

We begin with a photo from northbound I-5 approaching Blaine.  The upcoming exit (to WA hwy. 543, which heads due north to connect with British Columbia highway 15) leads to what is known as "Truck Customs".  Commercial traffic cannot use the I-5/B.C. 99 ("Peace Arch") border crossing:
Picture
Field/Nitzman, Aug. 2006
Historically, today's WA 543 carried US 99 traffic in Blaine.  This shot was looking north on WA 543, approaching the end of old US 99:
Picture
Jensen, 2001
Ahead at customs one would see the sign shown here (or, more accurately, a similar sign in the same location), at the original terminus on the Canada border:
Picture
Jensen, 2001
This next photo was looking the other direction, and it shows the north beginning of WA 543 (which was the north beginning of original US 99) from Canada:
Picture
Jensen, 2001
The Peace Arch border crossing was opened in the 1940s, and at some point the US 99 designation was routed onto the new road leading to it (which is now I-5).  Heading south from Canada, drivers who look closely at the Peace Arch might notice the inscription shown here:
Picture
Field/Nitzman, Aug. 2006
These photos were taken heading south from the Arch, approaching the north beginning of I-5 (and the former north beginning of US 99) at US Customs...

​...and these shots show northbound I-5 at the Canada border; the obelisk shown in this first photo is one of several in the area marking the international boundary:
Picture

Sanderson, Jul. 2021
That was the northern terminus of US 99 at the time of its decommissioning.  Ironically, one of the last remaining reminders of US 99's existence is in Canada: straight ahead is British Columbia hwy. 99.  The Peace Arch, for which this border crossing is named, is visible on the left side of the preceding photo, and here is a side-view:
Picture
Bozanich, Oct. 2001
The Peace Arch straddles the 49th parallel, upon which the international boundary was surveyed.  Visible in the lower right was a stone marker; the inscription is shown close-up here:
Picture
Bozanich, Oct. 2001
As of 2003, that marker had been temporarily removed -- or perhaps permanently -- for political reasons.  ​
In 1963, US 99 was temporarily truncated to Los Angeles, before the remainder of the US 99 designation in California was decommissioned in 1965.  Washington was the next state to eliminate US 99; below is the agenda item from AASHO's June 1969 meeting minutes:
Picture
That left only an orphaned segment of US 99 in Oregon, and that was formally decommissioned in Dec. 1971:
Picture
Even though US 99 has been gone for decades, there are still a few relics posted on the road.  One was in Seattle, at 1st Avenue and Columbia Street, above the onramp to the Alaskan Way Viaduct; this lasted until 2019:
