|History:||US 521 was born in 1932, running from US 21/NC 261 Pineville (current NC 51) south along Lancaster Hwy to the South Carolina Line. This short 5 mile stretch was cosigned as part of NC 26.
In late 1934, US 521 dropped its state route multiplex with NC 26.
In 1969, US 521 was extended north along South St, then west along the Billy Graham Pkwy to end at I-85. Sadly, this was 521's farthest reach at 19 miles.
In the vicinity of 1996, US 521 changed its route to multiplex with I-485 from Exit 65 to Exit 61, then proceed south along new construction to South Carolina where it met back up with Lancaster Hwy right around the state line. Lancaster Hwy from Exit 65 southward to the Palmetto State became unnumbered.
In 2003,, AASHTO approved US 521 north to be truncated to its current end at I-485 Exit 61. Everything north of Exit 65 is now unnumbered as primary routing, but the Billy Graham Parkway is still signed as Charlotte 4.
