History

Historically, SR 620 was known as Braddock Road. The road has historical significance in the American Civil War

, and portions of the road were established prior to British colonization of northern Virginia. Although the original Braddock Road was unified throughout its length, many portions of the original road have been transected, relocated or disjointed since the original path was defined (especially since the modern paved road system was constructed).

Establishment, including pre-colonization era

Braddock Road was originally composed of paths established by the Native American

 inhabitants of Northern Virginia. Later, British colonialists and Virginian governments developed and improved the paths into what became known as "Braddock's Road."

 troops traversed Braddock Road during various battles in Fairfax County and other parts of Northern Virginia.

One of Mosby's Raiders, Robert Spindle, was a native of Centreville. Later, the part of SR 620 that was formed when Braddock Road was cut at US 29 was named after him, Spindle Court.

The Modern Era

With the advent of the modern road system, Braddock Road changed. In the 1930s after the Virginia Secondary Road system was created Braddock Road in Fairfax and Loudoun Counties was given the designation SR 620.

In the 1960s I-66 was built coming through Centreville. At this point the section of SR 620 between SR28 south of I-66 and a point north of the new I-66 was deleted, and a new SR 620 entrance was created intersecting with SR 28 north of I-66.

When SR 28 was widened from a 4-lane highway to a 6-lane one SR 620 was changed again. SR 620 south of I-66 no longer intersected with SR 28; SR 620 ended where Willoughby Newton Drive is now.

In the 1980s a shopping center was built at the corner of U.S. 29 and Old Centreville Road. At that time the non-SR 620 section of Braddock Road was constructed linking SR 620 to Old Centreville Road. The intersection between SR 620 and U.S. 29 was cut, and this small portion of SR 620 was renamed Spindle Court.

In the 1990s New Braddock Road was constructed linking Union Mill Road to SR 28. This is when SR 620 was cut, so that, on the east side of Union Mill Road, the road is Braddock Road, and on the west side it's New Braddock Road. Braddock Road heading west now intersects with Union Mill Road one block to the north.

The final change came in 2009. A barrier was erected on SR 28 that forced all traffic coming from SR 620 from the west to turn south on SR 28.
