The Oregon bridges found along the coast are some of the state's most famous landmarks. Today, most if not all of the Oregon bridges are painted a dark navy green. This page provides photographs of many of the state's historically significant bridges. Oregon has more than 200 bridges eligible to be listed on the National Register of Historic Places. The majority of the beautiful bridges along the Oregon Coast were designed by Conde B. McCullough in the early 1930's. The O.D.O.T. (Oregon Department of Transportation) is responsible for maintaining these bridges. The wet humid climate of the Oregon coastline forced O.D.O.T. to make changes on maintaining these bridges or else they could easily be lost. Making an extensive check of the bridges most apt to be in threat the department undertook some new procedures. Some but not all of these procedures involved include precasting of replaceable parts, composite strengthening, and many other methods. Thankfully to O.D.O.T. many of these bridges have been saved and preserved back to their original condition.

Below is a bit of information about some of the bridges:

The Alsea Bay Bridge was started in 1988 and completed in 1991. The bridge has bold Y-shaped piers and a towering arch at its center. This was the first bridge that Conde McCullough designed to replace the Old Alsea Bay Bridge.

Big Creek Bridge's main span is 120 feet of reinforced concrete throughout a tied arch - it has an elliptical shape. This was one of the first reinforced tied arch spans to be built in this country. The bridge is 235 feet total, designed by Conde McCullough and built by the Union Bride Company.

Cape Creek Bridge: This bridge goes over Cape Creek and is one of Conde McCullough's most unique designs. The bridge runs over the creek into the Creek Tunnel on highway 101. The span of the bridge is 619 feet. The bridge was constructed by John K. Holt and the Clackamas Construction Co.

The Columbia River (Astoria) is also known as the Astoria-Megler Bridge. It is a bit over four miles long and is the longest bridge in Oregon. This bridge connects Oregon and Washington State. It was designed jointly by the Oregon and Washington State highway departments.
