Several, at the time of their completion, attracted worldwide attention and the praise of professional engineers, influencing the course of bridge construction.

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 tolls3 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.
