# List of bridges on U.S. Route 101 in Oregon

This is a list of bridges and tunnels longer than 100 feet (30 m)yes, it is a little arbitrary, but it ensures that all bridges that were listed continue to be listed while not including too many minor ones on U.S. Route 101 in Oregon, also known as the Oregon Coast Highway, from south to north. Many of them were designed by Conde McCullough.
