Mileage: in 1989 AASHTO listed a figure of 194 miles for US 521... however, that included the mileage of US 521's associated business route.  According to the state subtotals on AASHTO's 1989 spreadsheet, mainline US 521's actual end-to-end total was 191 miles... but that was during the brief timeframe when US 521 went all the way up to Billy Graham Pkwy.  Since then it has been truncated a couple times, and our own 2020 measurement yielded 176.6 miles.  
US 521 was commissioned in 1932; its south end has always been in Georgetown:

These photos were taken looking east on Highmarket Street.  US 521 ends at its junction with US 17, which is the intersection ahead (Fraser Street): ​

Formerly that junction was signed properly (first photo); it is unclear why the more recent replacement (second photo) was changed to "TO US 17", when Fraser is US 17... as the signage ahead attests:
Picture
Karners, Apr. 2014
And that was not the only signage failure, as we will see below.  But first: in about 1968, the US 521 designation was extended straight ahead on Highmarket.  Through the 1990s, US 521 was signed both directions from US 17 on Highmarket, although there may not have been any US 521 signage east of that junction.  This image was looking east on Church Street, or south on US 17:

Karners, Jan. 2017
US 17 curves to the right, but to the left on St. James Street was the south beginning of US 521 for a period of about 30 years.  Apparently that segment was truncated around 2000, when US 521 signage from Fraser began pointing only to the west on Highmarket.  These photos were from northbound Fraser/US 17:

Karners, Apr. 2014
​That first photo shows an assembly that replaced a structurally-identical one which was there at least through 2000.  (Incidentally, about one block ahead, overhead signage for the south beginning of US 701 is visible.)  But for some reason, this more recent replacement indicates that Highmarket is actually US 17A, leading TO US 521:
Picture
Karners, Apr. 2014
But the truth is, about two blocks to the left, US 17A comes in via Exchange Street, and joins US 521 along Highmarket.  The first confirming marker is just past that junction.  ​The two routes are overlapped for about ten miles, where they diverge at Sampit. 

Originally the north end of US 521 was in Pineville (just south of Charlotte):
Picture
c. 1940, NC DoT
At the time, US 21 came in from the west on Main Street, or modern NC hwy. 51, and then went north along Polk Street (which soon becomes South Boulevard). This image was looking west on Main:
Picture
Buchanan/Ivy/Nitzman, Nov. 2021
A pretty nondescript intersection now, but originally that was northbound US 21, which continued to the left on Polk.  To the right on Polk was the north beginning of US 521.

​In 1968, US 521 was extended straight ahead, initially overlapped with US 21 into downtown Charlotte.  But the US 21 designation was gradually shifted over to what is now I-77 (as segments of that freeway were opened to traffic), leaving only US 521 on South Blvd:
Picture
c. 1970, NC DoT
At Morehead Street, US 521 turned west, ending at Graham Street, where it junctioned US 29.  Graham no longer connects with Morehead (because of the nearby stadium and I-277); this image shows what is there now:
That is looking east on Morehead, or north on US 29, which today continues by turning left on Mint Street, on the far side of the freeway overpass.  But historically, US 29 turned left just on this side of the overpass, at what is now an entrance to the stadium, but was once Graham Street.  So the north beginning of US 521 was straight ahead.
That was the case until 1976.  Then northbound US 521 traffic was directed to turn west on Woodlawn Road, passing through I-77's interchange 6, and ending at Tryon Street (NC 49).  Here is a modern view of that junction:
Picture
Buchanan/Ivy/Nitzman, Nov. 2021
That was looking west on Billy Graham Parkway; Woodlawn begins straight ahead, and historically that direction was also the north beginning of US 521.  This next photo was looking north on Tryon:
Picture
Buchanan/Ivy/Nitzman, Nov. 2021
For a few years, the north beginning of US 521 was to the right on Woodlawn.  But then in 1984, when Billy Graham (to the left) was completed, US 521 was extended that direction to a new terminus at I-85's interchange 33:
Picturec. 1990, NC DoT

These shots were looking north on BGP.  There was no "End" sign... well, at least not for the end of US 521:

These photos show the exit from I-85 (northbound and southbound, respectively), as well as the first US 521 marker heading south on BGP:

Field/Nitzman, Oct. 2001
When the I-485 loop was complete through the area and Johnston Road was built as a new four-lane connector, US 521 was switched over to Johnston and then overlapped with I-485 to South Blvd, allowing traffic to bypass Pineville and a large segment of the original routing.  Then in 2003, when the west loop of 485 was completed (joining 77 and 85), US 521 was truncated to its interchange with I-485 (exit 61).  This photo shows the spot... 
Picture
Nitzman, May 2005
...although at that time the sign still reflected US 521's concurrency with westbound I-485.  Just ahead, an "End" sign was posted:
