US 101 Duckabush River WA bridge (#1456)

US 101 Duckabush River WA bridge (#1456)
There was nothing particularly special about this bridge other than that it is the style of bridge architecture used for crossings of relatively narrow rivers on US 101 throughout Oregon and Washington. Per Bridgehunter.com (an excellent resource), this is a 'rainbow arch bridge' and was built in 1934. Website: bridgehunter.com/wa/jefferson/1764B0000000

I had only seen this particular type of concrete construction on US-101 in Oregon and Washington, but apparently they're relatively common. A rainbow arch is a variation on a through arch, both of which seem to be basically a standard arch bridge like found everywhere, but with the arch above the roadway instead of below. The Wikipedia page lists two in England. Bridgehunter has many pictures of 'rainbow arch', though some are classified incorrectly.
