Colonial Parkway

Colonial Parkway is a 23-mile (37 km) scenic parkway linking the three points of Virginia's Historic Triangle, Jamestown, Williamsburg, and Yorktown. It is part of the National Park Service's Colonial National Historical Park. Virginia's official state classification for the parkway is State Route 90003. With portions built between 1930 and 1957, it links the three communities via a roadway shielded from views of commercial development. The roadway is toll-free, is free of semi trucks, and has speed limits of around 35 to 45 mph (55 to 70 km/h). As a National Scenic Byway and All-American Road (one of only 31 in the U.S.), it is also popular with tourists due to the James River and York River ends of the parkway.

For most roads it crosses it does not have an intersection with that road. It normally goes on a bridge, under a bridge, or in a tunnel (the only tunnel runs beneath Colonial Williamsburg). Examples of this happening: when it crosses Interstate 64 and US Route 60. When it crosses a road (if it even has an intersection with it) it is more like an interchange than a crossroad. Almost every overpass is made of brick and made to look like it was made in the Colonial era (most roads that go over the Colonial Parkway instead of the bridges that the Colonial Parkway uses to travel over other roads, like Interstate 64). It resembles a Colonial trail or wagon road in the Colonial era with most of the wildlife and animals at the York River and the James River (at the ends or near the ends). The Parkway is a connector of Virginia's Historic Triangle and other roads or the Jamestown Ferry (to State Route 10).

Since the Parkway is intended primarily for sightseeing, and only secondarily as a through route to the historic points, there are many scenic pull-offs with historical markers giving brief descriptions of the view. The more popular pull-offs are near the James River and York River ends of the parkway, where there are panoramic views across each river. The Colonial Parkway is mostly covered by trees. It is very shady in the spring and summer and just as beautiful in the fall and winter. The western end of the parkway begins at Jamestown, on Jamestown Island (see image), where the Virginia Colony was begun in 1607 on the shore of the James River. Some visitors begin their experience by approaching the entire area from the south via State Route 10 to Surry, and then across the James River and arriving by water on the Jamestown Ferry. The middle point of the Parkway is at Williamsburg, where the capital of Virginia Colony was moved in 1699, from Jamestown. The parkway tunnels under the historic district of Colonial Williamsburg. The eastern end of the Parkway is at Yorktown, where General Cornwallis surrendered to George Washington in 1781 towards the completion of the American Revolution.

The Colonial Parkway is free of trucks and commercial vehicles except passenger-carrying buses. The speed limit, 45 mph on most of the Parkway and 35 mph in a few areas, is enforced by the National Park Service law enforcement rangers. With limited exits and no traffic lights or stop signs, the parkway is at certain times of day a busy short-cut for local traffic and commuters. It has no painted traffic lane-marking lines, and some stretches are posted "Pass With Care". The unmarked pavement is made of rounded "river gravel" set in a concrete-mix, providing an unusual earth tone color. Despite a federal policy instituted late in the 20th century of requiring user fees at many National Parks and Monuments, the Colonial Parkway has remained toll-free.

The Colonial Parkway took over 25 years to create from concept to completion.

In 1930, a survey of the area was undertaken by National Park Service (NPS) engineering and landscape architect professionals for a 500-foot (150 m) right-of-way for the parkway. Between Yorktown and Williamsburg, the initial proposals called for the parkway to follow an inland route along colonial-era roads. However, instead, it was decided to align the road along the York River through U.S. Navy land to avoid grade crossings, extensive tangents, modern intrusions and other "visual junk". This land included the Naval Weapons Station (Yorktown) and the former E.I. DuPont explosives factory and town complex at Penniman, Virginia which later became known as Cheatham Annex.

Following the parkway concept of Calvert Vaux and Frederick Law Olmsted, designers of New York City's Central Park, the planners of the Colonial Parkway used a model of a limited-access highway with broad sweeping curves, set in a landscaped right-of-way devoid of commercial development. These features, derived from 19th-century Romantic landscape theories, created a safer and more pleasant drive compared to the increasingly congested urban strips. In addition to protecting the views, culvert headwalls and parkway underpasses were clad in "Virginia-style" brick laid in English and Flemish bonds to promote a "colonial-era" effect. Design features such as molded coping rails, string courses and buttresses followed the historical prototypes found at Williamsburg.

The land for ten miles (16 km) of the route between Yorktown and Williamsburg was given to the NPS free of charge, and construction began first on this portion. By 1937, the road was completed to just outside Williamsburg. There was some debate over the routing in the Williamsburg area, and eventually a tunnel was selected. The tunnel under the historic district of Colonial Williamsburg was completed by 1942, but opening was delayed by World War II and some structural and flooding problems. It finally opened for traffic in 1949, leaving only the Williamsburg-to-Jamestown section to be built.
