  • NO FIREWORKS

    Reminder to park visitors. Fireworks are prohibited at Prince William Forest Park.

  • Oak Ridge Campground Site A29 closure

    Oak Ridge Campground site A29 will be closed until safety concerns have been mitigated. Please do not use that site until it has been reopened.

  • Warm Wet Spring = More Ticks

    Please check yourself and your pets for ticks continually during and after your visit. Ticks are less prevelent if you stay on trail or in mowed areas. Wearing light colored clothing helps you spot them before the attach.

  • Firewood

    Outside firewood is prohibited in Prince William Forest Park, unless it is certified USDA 'bug free' firewood. Dead and downed wood may be collected from designated areas for use while in the park. Help us protect the forest from invasive species!

  • Visitor Center Remodel 2014

    Over the next several months there will be new changes coming to the Visitor Center. Presently we are remodeling the bookstore area to give it more of a country theme. Next the exibit area will get all new exhibits. Thank you for your patience and support

The following information is from a Historic American Building Survey Report taken in 1988 by Mary Kendall Shipe.

The South Branch Quantico Creek Bridge spans Quantico Creek along NPS Route 11, the main thoroughfare through Prince William Forest Park. The structure's configuration consists of a Pratt pony truss. The construction material of the truss is finished standardized timbers which have been creosoted.(1) The bridge measures sixty-two feet in length. The top chord of the truss rises twelve feet nine inches above the bridge deck; this height decreases to eight feet ten inches at the posts where the next two chords meet. The bottom chords on either side are thirteen feet long and the three middle chords are each twelve feet in length. The center section of the truss has cross-bracing; both diagonal members of the bracing have lengths of seventeen feet seven inches and help the structure support tension loads. The cross-bracing is supported by vertical timbers (four feet by fourteen feet) on either side. These timbers, connected with bolts of malleable iron in ring connections, act in compression. The center cross-bracing is adjoined on either side by a brace connected to another vertical post member which is eight feet ten inches in length. Railings (three inches by eight inches) further strengthen the structure from end to end. The deck of the bridge is supported underneath by timber cross-bracing and is approximately twenty feet wide. The original wood decking has been covered with asphalt. The bridge has concrete abutments on each end.

In the early twentieth century the establishment of recreational camping facilities in the vicinity of large cities offered low-income families a respite from urban life. This idea arose from the promotion of nature as a vacation destination. In 1916, one article reported that "tourists seeking beauty spots are being directed by the government to national forests as vacation grounds (2). By 1934, the National Park Service had chosen such a park area for the Washington, D.C. region. The Chopawamsic Recreational Demonstration Area (later renamed Prince William Forest Park) contained approximately 15,000 acres, a typical size for these experimental demonstration areas. The Recreational Demonstration Area (RDA) program employed the use of the Civilian Conservation Corps (CCC) under the Federal Emergency Relief Administration, a program of Franklin D. Roosevelt's administration. The cec received praise for "endowing them [parks throughout the nation] with fine roads, picturesque paths and bridges (3).

Crucial to the early development of Prince William Forest Park, the eec gave the park its original plan which it closely resembles today. The plan's primary initial goals included the establishment of camps and the construction of a main loop road through the park. The South Branch Quantico Greek Bridge, erected where the park road crosses the south branch of the creek, was constructed between 1939 and 19404 during the initial stages of the park's development. According to a former CGC worker, GCG laborers raised the bridge, (5)thus numbering the bridge among many of the GGC-constructed structures of Prince William Forest Park. Judging by reports, the CGC technicians in the park were considered "excellent designers (6).

In design, the South Branch Quantico Creek Bridge is indicative of park bridges of its period. Several stylistic considerations present during the 1930s and early 1940s affected park bridge construction, one being the availability of natural or "native" materials in parks under development. An original proposal for Ghopawamsic RDA noted that quality building materials (such as stone, sand, gravel, rock and lumber) were plentiful and were "native and at hand without extra cost (7). The park architects and designers of the National Park Service at this time endorsed the appearance of bridges obtained from avaigable materials: "a native material's look, always desirable in park bridges." The prevalent materials for bridges in national parks had been identified as stone and timber. The quality and quantity of building materials thus had more importance than the material's "nativeness."

By 1935, a certain style of architecture was utilized throughout national parks and forests. For lack of a more appr~priate term, the style became loosely referred to as "rustic" architecture. Rustic architectural theory objected to open wood truss bridges because trusses were thought to confuse the design of the bridge and hinder its cooperation with the natural surroundings. Practical considerations also furthered the argument against this design: wood trusses were difficult to maintain and generally had a short life span. Aside from its use of timber, the South Branch Quantico Greek Bridge does not demonstrate much of the influence of the rustic style, but it does manifest a basic tenet of rustic architecture: "it allowed the development of necessary park facilities without needless disruption of the natural scene (10).

CCC architecture and engineering in Prince William Forest Park included camp buildings, administrative facilities, utility buildings, bridges, roads and trails. The South Branch Quantico Creek Bridge is sympathetic in design and construction to other examples of CCC architecture in the park. Aside from several possible influences discussed, the bridge most strongly reflects the utilitarian nature of CCC construction.

9 Albert Good, the National Park Service architect of this period, defined the term: "Successfully handled, it is a style which, through the use of native materials in proper scale, and through avoidance of rigid, straight lines and over sophistication, gives the feeling of having been executed by pioneer craftsmen with limited hand tools. It thus achieves sympathy with natural surroundings and with the past." (National Park Service, Park Structures and Facilities, [Washington, D.C.:1935l, pp. 3-4.)

Did You Know?

Pyrite

Because of its abundance and high sulfur content, Pyrite, also known as "Fool's Gold," was once mined in what is now Prince William Forest Park (1889-1920) to be used in products ranging from light bulbs to soap.
