Description
Alpowa Creek was first bridged in 1923 when this rainbow arch structure, consisting of two 100 foot spans, was built by the Pacific Construction Company of Spokane. The bridge is a half through structure on which the roadway is suspended at the midpoint of the ring arches from concrete beams. Constructing a bridge of this type requires a great deal of skill and complex formwork. Few were built in the inland northwest.Timothy, who was born Temuutsu, led the Alpowa band of Nez Perce. He was the first of his people converted to Christianity by Henry H. Spalding and is credited with the rescue of surviving cavalry troopers after the defeat of Colonel Steptoe’s detachment by a combined force of Spokane, Couer d’Alene and Palouse Indians at the battle of Rosalia in 1858. His daughter, Jane, guided a party headed by E.D. Pierce to the upper Clearwater in 1860. Their discovery, near Orofino, set off the first Idaho gold rush. Jane later married John Silcott who started a Snake River ferry at the mouth of Alpowa creek in 1861.
E.V.Kuykendall, a Pomeroy lawyer, was Washington’s Director of Public Works when the bridge was planned. He was instrumental in the designation of the bridge as a memorial to Timothy in the authorizing legislation.
The town of Silcott was demolished and the highway was relocated prior to the completion of Lower Granite Dam in 1974. The Indian Timothy Bridge was bypassed and is preserved in place as an example of rare bridge architecture.

Comments
Some Marsh Arch Bridges have a brace between the arches and some do not. It generally depends on the span length.
There are a few factors that distinguish a Marsh Arch from a regular rainbow arch. Perhaps the main difference is the fact that Marsh Arch Bridges use a special type of reinforcing. There is actually a bonafide steel arch structure under that concrete instead of just rebar.
I could be wrong but doesn't a Marsh Arch have a element across the top between the arch tops.
Since Marsh isn't listed as the engineer a/o builder it may not carry the name. I consider any of the concrete arches of this type to go by the name Marsh just as we use Pratt even if not built by them. If there is a consistent classification we use on this site I'll always try to follow the convention.
Just my $0.02 - but this appears to be a Rainbow Arch, but not a Marsh Arch.
There is no category for Marsh pony arch so choosing Marsh Arch automatically determines "through" but Marsh can be added manually.
Shouldn't this be listed as a pony arch rather than a through arch?

Robert is correct. There are several small scale Marsh arches in Iowa with no bracing.
