Depoe Bay Bridge, Deck arch bridge in Depoe Bay, US.

Depoe Bay Bridge is a reinforced concrete arch structure that stretches 312 feet (95 meters) over the Pacific and links both sides of Highway 101. The structure uses arches to span the entrance of the harbor between the two sides of the bay.

Conde McCullough designed the bridge for the Oregon Coast Highway, and the original concrete arch span opened in 1927 at just 18 feet wide with no sidewalks. Sightseers stopping for the bay view caused congestion, so in 1940 a matching arch was built alongside, offset slightly south because of the slanted channel. The widened deck reached 48 feet with sidewalks, and the crossing joined the National Register of Historic Places in 2005.

The deck's arched railing carries Art Moderne detailing, a style popular in the 1930s and chosen to match McCullough's original design when the second span was added in 1940. The two halves were joined only at the top, and the new arch and girders sit a few metres south because the channel runs at an angle to the bridge.

The bridge has sidewalks on both sides and a lower pedestrian walkway, giving walkers a clear view of the harbor entrance below. From these vantage points you can observe the small working harbor and watch the ocean and its marine life.

The 1940 widening was built by the Odom Construction Company, which added stairs and a walkway under the bridge leading to the Depoe Bay Whale Watching Center. The original 1927 span cost $55,000 and was built by the Kuckenberg-Wittman Company. The bridge was listed on the National Register of Historic Places on August 5, 2005.
