The road is 288 kilometers long.

Travel directions

In the coastal town of Georgetown, US 521 begins at an intersection with US 17, the coastal route from Charleston to Myrtle Beach. The US 701 that leads to Conway also begins here. US 521 is then a 2×2 road to the west, through a heavily wooded area. After Andrews the road narrows to 1×2 lanes and the road runs alongside the River Black. At Greeleyville, you cross the 2×2 US 52, which runs from Charleston to Florence. After this, US 521 again has 2×2 lanes and crosses Interstate 95 at Manning, about 30 kilometers further west., the highway from Savannah to Fayetteville. After this, US 521 bends northwest and runs in 2×2 lanes to Sumter, a town with 39,000 inhabitants, 25 kilometers away.

Sumter is a major interchange, US 15 comes here from Savannah and runs to Bennettsville, US 76 comes from Columbia and runs to Florence, US 378 runs to Myrtle Beach and US 401 runs to Bennettsville. After Sumter, the road narrows again to 2×1 lanes and continues for 25 miles to Camden, a small town on Interstate 20, the highway from Columbia to Florence. Parallel to this runs the US 1, which one also crosses. After this, US 521 heads north through wooded land via Lancaster to Charlotte. From Lancaster, the road again has 2×2 lanes and the US 521 ends on the ring ofCharlotte, North Carolina, Interstate 485.


US 521 was added to the US Highway network in 1932 and ran from Georgetown, South Carolina to Pineville, North Carolina. The South Carolina route has not changed since, the North Carolina terminus was changed to nearby Charlotte in 1968.

The US 521 is characterized by various double numberings. The first upgrade was a bypass of Lancaster in the north of the state in the early 1960s, followed by a short widening to 2×2 lanes north of Lancaster in the early 1970s. This was extended northwards in the North Carolina border area in the late 1970s to early 1980s. Presumably in the early 1990s, the double numbering with the US 17 Alternate west of Georgetown was widened to 2×2 lanes. Also, in the late 1980s or early 1990s, a small section north of Sumter and a section around Camden was widened to 2×2 lanes. Also at the time, the entire 35-kilometer route from Lancaster to the North Carolina border had 2×2 lanes.

In North Carolina, US 521 was built around 1995-1996 on the south side of Charlotte on a new route that connected to the new Interstate 485. This effectively led the entire US 521 in North Carolina over a new route. In 2004, US 521 was shortened and has since ended at I-485 and no longer in Downtown Charlotte.

After 2000, several upgrades to US 521 were made in South Carolina. Around 2000, a 13-kilometer section between Sampit and Andrews was widened to 2×2 lanes. An incomplete bypass of Andrews was also constructed at that time. Around 2005, a 20-kilometer stretch between Greeleyville and Manning was widened to 2×2 lanes. In the same period, the section between I-95 and Sumter in the nearby region was also widened to 2×2 lanes over a distance of 30 kilometers.
