Virginia State Route 20 (SR 20) is a primary state highway in the Commonwealth of Virginia, United States. The route extends approximately 75 mi (121 km) from its western terminus at U.S. Route 15 (US 15) in the town of Warrenton, Fauquier County, to its eastern terminus at U.S. Route 1 (US 1) near the community of Woodford in Caroline County.
Route description
- Western segment: SR 20 begins at US 15 on the western edge of Warrenton and proceeds eastward as a two‑lane rural highway, passing through the unincorporated communities of Cedar Run and Marshall.
- Central segment: The route continues southeast, crossing the Rappahannock River near the town of Rappahannock and intersecting State Route 3 (SR 3). It then enters Culpeper County, where it serves the town of Culpeper, intersecting U.S. Route 29 Business (US 29 Bus.) and U.S. Route 15 (US 15) again.
- Eastern segment: From Culpeper, SR 20 proceeds eastward through Orange County, passing near Lake Anna, and then enters Caroline County. The highway traverses the communities of Port Royal and Heathsville before reaching its eastern end at US 1 near Woodford.
Historical overview
- The highway was incorporated into Virginia’s primary state highway system during the 1930s, as part of a statewide effort to improve east‑west connectivity between the Shenandoah Valley and the Eastern Shore region.
- Original alignments followed older county roads and stagecoach routes that linked Warrenton to the Rappahannock River crossings.
- Over the decades, SR 20 has been realigned in several locations to bypass town centers and to accommodate new bridge structures, notably the 1995 replacement of the Rappahannock River bridge near Port Royal.
- No major renumbering of the route has occurred since its initial designation; it has retained the SR 20 designation throughout its existence.

Traffic and maintenance
The Virginia Department of Transportation (VDOT) maintains SR 20. Traffic volumes are generally low to moderate, with higher counts in the Culpeper and Port Royal sections, reflecting local commuter and agricultural traffic. The roadway is primarily two lanes, with occasional passing lanes and shoulder improvements near intersections and bridge approaches.
Significance
SR 20 provides an important corridor for intra‑regional travel, linking several county seats (Warrenton, Culpeper, and Port Royal) and serving as an alternate route to the more heavily trafficked US 29 and I‑66 for east‑west movements across central Virginia. The route also provides access to recreational sites such as Lake Anna State Park and historical sites in Port Royal.
