Gilberts Corner is an unincorporated area at the intersection of U.S. Route 50 and U.S. Route 15 in Loudoun County, Virginia, located east of the historic village of Aldie. There are no residences at this intersection, but its name is attributed to the surrounding area. Gilberts Corner is named after the William Gilbert family, who ran the gas station/restaurant that sits at the northeast quadrant of the crossroads. It gained prominence in the 1920s when the Carolina Road (now Watson Road) was a toll road and U.S. Route 15 was extended south from Leesburg to U.S. Route 50. Due to increased traffic from toll evaders, U.S. Route 15 eventually was extended even farther south. The gas station/restaurant closed in the 1980s and is currently in the process of being renovated. Due to heavy traffic in the area, many commuters avoided the intersection altogether by going through Lenah and taking U.S. Route 15 south.

The Little River Turnpike Bridge carries U.S. Route 50 (US 50) across the Little River near Aldie in Loudoun County, Virginia. The two-arch masonry bridge was built in 1826 by the Little River Turnpike Company, which built the roadway that is now US 50. The costs of the bridge were apparently shared between that company and the Ashley's Gap Turnpike Company. It is one of a small number of masonry arch bridges still carrying a major through road in the state. It is about 108 feet (33 m) long and 23 feet (7.0 m) wide.The bridge has received only modest visible modifications since its construction. Concrete caps have been installed on upper surface elements, and the arch underside has also been protected with shotcrete. The upstream central pier has had a concrete fender added to protect it from debris and scouring. The downstream parapet wall was damaged by a truck in 1998 and reconstructed, and in 2004 reinforcing metal rods were injected into the rubble of the bridge to help distribute the active load. As of 2014, the bridge has no weight limit.The bridge was listed on the National Register of Historic Places in 2014.

Little River is a 23.4-mile-long (37.7 km) tributary stream of Goose Creek in Fauquier and Loudoun counties in northern Virginia. Via Goose Creek, it is a tributary of the Potomac River. The stream rises to the east of Marshall in Fauquier County and flows northwards along the western base of the Bull Run Mountains to Aldie, where it passes between the Bull Run Mountains and Catoctin Mountain. It then flows northward along the eastern slope of the latter mountain, joining Goose Creek east of Oatlands. The Little River Turnpike (present-day U.S. Route 50/State Route 236) derives its name from the stream, as its western terminus was at the Little River in Aldie where it intersected the Ashby's Gap Turnpike and Snickersville Turnpike.

Aldie is an unincorporated community and census-designated place (CDP) located between Chantilly and Middleburg in Loudoun County, Virginia, United States. The historic village of Aldie is located on the John Mosby Highway (U.S. Route 50) in a gap between the Catoctin Mountains and Bull Run Mountains, through which the Little River flows. Aldie traditionally serves as the gateway to the Loudoun Valley and beyond. The Aldie CDP was first drawn prior to the 2020 census and comprises solely the historic village. As of 2014, the Aldie postal area (ZIP Code 20105), covering a much greater area than the CDP, had a population of 11,420 people, a 569% increase since 2000 making it one of the fastest-growing suburbs in the Washington, D.C. metropolitan area and the second fastest growing ZIP code in Virginia. The Aldie ZIP Code 20105 has currently the highest median sales prices for houses sold in Loudoun County. As a result, the eastern part is suburbanized with numerous upscale communities recently built or under construction while most of the Aldie Hills adjacent to the village of Aldie have so far largely preserved their bucolic character with farms, wineries and custom homes. It was first listed as a CDP in the 2020 census with a population of 70.
