Historic American Engineering Record
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS) responsible for administering the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, and are archived in the Prints and Photographs Division of the Library of Congress. Historic American Buildings Survey In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive make-work program for architects, draftsmen and photographers left jobless by the Great Depression. It was supported through the Historic Sites Act of 1935. Guided by field instructions from Washington, D.C., the first HABS recorders were tasked with docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walton, Oregon
Walton is an unincorporated community in Lane County, Oregon, United States. It is located halfway between Eugene and Florence on Oregon Route 126. Construction of Route 126 began in 1881, and after it crossed the Oregon Coast Range near Noti, it followed a tributary of the Siuslaw River named Walton Creek.

Whipple Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Hayden Bridge (Springfield, Oregon)
The Hayden RR Bridge, is a truss bridge located in Springfield, Oregon, spanning over the McKenzie River (Oregon), McKenzie River. The bridge initially served as a traditional railroad bridge, starting as part of the first transcontinental railroad in Utah, before being shipped to its current location to serve as part of the Marcola line, whose primary use was the distribution of lumber. It later closed down due to the closure of the area's lumbermills, until it was converted into a pedestrian bridge in 2019. It is one of the few remaining wrought-iron, Phoenixville bridges still standing, and the oldest intact bridge in the state of Oregon. Location Hayden Bridge is located in Springfield, Oregon, near the intersection of the Marcola, Old Mohawk, and Camp Creek roads. Its milepost was 649.50 on the Southern Pacific Railroad when it comprised part of the railroad during its use as a railroad bridge. The bridge spans the McKenzie river, where it runs parallel to a road bridge c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horse Creek Bridge (McKenzie Bridge, Oregon)
The Horse Creek Bridge was a covered bridge near the unincorporated community of McKenzie Bridge in Lane County in the U.S. state of Oregon. Built in 1930, the structure, long, carried Horse Creek Road over Horse Creek. The creek is a tributary of the McKenzie River. Bypassed by a concrete bridge in 1968, Horse Creek Bridge was not dismantled until 1987. During the intervening years, it served as a pedestrian bridge. Its timbers were donated to the City of Cottage Grove, which used some of them to build a small covered bridge in a park. The remaining timbers were given to the City of Myrtle Creek in 1990 for a covered bridge over Myrtle Creek. The bridge connects a parking area to the city's Mill Site Park. The creek is a tributary of the South Umpqua River. The 1930 bridge was added to the National Register of Historic Places in 1979 and removed after 1987.

Lincoln County, Oregon
Lincoln County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, its population was 50,395. The county seat is Newport. The county is named for Abraham Lincoln, 16th president of the United States. Lincoln County includes the Newport, Oregon Micropolitan Statistical Area.

In 1896 it was chosen as the permanent county seat. Three elections were held to determine if the county seat should be moved from Toledo to Newport. Twice these votes failed—in 1928 and 1938. In 1954, however, the vote went in Newport's favor. While Toledo has remained the industrial hub of Lincoln County, the city has never regained the position it once had. Like Tillamo ...

Alsea Bay Bridge
The Alsea Bay Bridge is a concrete arch bridge that spans the Alsea Bay on U.S. Route 101 (US 101) near Waldport, Oregon. History There have been two bridges on this site. The first bridge was designed by Conde McCullough and opened in 1936. It was a long, reinforced-concrete combination deck and through arch bridge. The hostile environment caused significant corrosion to the steel reinforcements. In 1972 the Oregon Department of Transportation began projects aimed at extending the life of the bridge. By the mid-1980s it was decided to replace the bridge rather than continuing costly rehabilitation efforts. The first bridge was demolished in 1991. Construction of the second bridge, designed by HNTB, began in 1988, and it was opened in the fall of 1991 at a cost of $42.4 million. The bridge is in total length, with a main span that provides of vertical clearance. The bridge has a latex concrete deck and the piers are significantly thicker than normal in an ...
