The Colonial Parkway, a 23-mile scenic three-lane highway, connects Yorktown Battlefield, Colonial Williamsburg and Historic Jamestowne. (These three sites are known as the Historic Triangle.) The Parkway starts at the Yorktown Battlefield Visitor Center parking, heads west following the York River to Williamsburg, turns south to follow the James River, and ends up in the Historic Jamestowne Visitor Center parking lot.
The National Park Service maintains and patrols the Parkway. Pull-offs of historical significance along the Parkway provides scenic views and historical information. In keeping with the natural beauty and the Colonial atmosphere of the route, the three-line roadway is not marked with white or yellow dividing lines. Composed of a cobble aggregate pavement, the highway simulates an early Colonial Virginia roadway and can present a rough, bumpy ride for bicyclists. The center lane of this three-lane roadway is for passing only; signs indicate no passing zones.
