Designed first and foremost to be practical, bridges nevertheless are often breathtaking in their construction, combining function and aesthetics. The historic structures that span the Evergreen State's highways are no exception. These technological wonders are extraordinary by any measure, yet their stories have remained largely unknown. Conceived by visionary engineers and built by anonymous workmen, Washington's highway bridges are amazing triumphs of skill, and played a significant role in the state's history. Several, at the time of their completion, attracted worldwide attention and the praise of professional engineers, influencing the course of bridge construction. In their quest to compile the first comprehensive history of the state's highway bridges, the authors poured through the extensive records at the Washington State Department of Transportation (WSDOT), collecting definitive documentation and photographs from across the state. This magnificent book, including more than 100 illustrations, represents the culmination of years of study by many individuals associated with WSDOT and the Office of Archaeology and Historic Preservation (Olympia).

Michigan's historic highway bridges are rapidly being torn down and replaced as they deteriorate or become unable to support increased traffic volumes and loads. While the state has the responsibility of providing safe bridges, historian Charles K. Hyde maintains that the state must also preserve many of these remaining historic structures to insure that future generations will have them to view and appreciate. In Historic Highway Bridges of Michigan, Hyde identifies Michigan's historically significant highway bridges within the broader contexts of American bridge design and construction in the 19th and 20th centuries. The book summarizes the improvement of highway bridge design in the United States and compares Michigan's experiences with national trends. To aid the reader interested in visiting the historic highway bridges of Michigan, regional maps show the location of bridges included in the text.

Rugged individuals armed with hand tools, sweat, and ambition began building covered bridges in Oregon during the mid-1850s. These bridge builders often camped out at remote sites, living off the land or contracting with local farmers for food. Early owners of covered bridges financed construction by charging tolls—3¢ for a sheep, 5¢ for a horse and rider, and 10¢ for a team of horses and wagon. In the early 20th century, the state provided standard bridge and truss designs to each county, and most of the resulting structures incorporated the Howe truss. With the abundance of Douglas fir and the shortage of steel during the world wars, the construction of wooden covered bridges continued well into the 1950s, mainly in the Willamette Valley. During the 1920s, Oregon boasted more than 350 covered bridges.

In the 1920s and 1930s, Oregon's legendary bridge engineer Conde B. McCullough designed a first-rate collection of aesthetic bridges on the Oregon Coast Highway to enhance an already dramatic and beautiful landscape. The six largest of these, at Gold Beach, Newport, Waldport, Florence, Reedsport, and Coos Bay, eliminated the last ferries on the Oregon Coast Highway between the Columbia River and California. McCullough planned to build one bridge each year after completion of the Rogue River Bridge at Gold Beach in 1932, but the tightening grip of the Depression threatened his plans. In 1933, McCullough and his staff worked day and night to finish plans for the remaining five bridges, and in early 1934, the Public Works Administration funded simultaneous construction of them. The combined projects provided approximately 630 jobs, but at least six workers perished during construction. After the bridges were complete, Oregon coast tourism increased by a dramatic 72 percent in the first year.
