The 1991 version of the Alsea Bay Bridge was designed with many unique characteristics that both created a sleek modern bridge and reminded the public of the lost tied arch bridge that once stood on the site.
The most important aspects of the new design included the main steel through arch and the included “Y” piers that gave the bridge a unique appearance yet still gave a since of bridge continuity throughout Oregon’s Pacific Coast Highway.
