Essay 

From "A Century of Covered Bridges" by Lee H. Nelson

The old Knights' Bridge was certainly one of Oregon's best-known covered bridges. Its very longevity earned it a special place in the hearts of those nostalgically inclined to admire the pioneer concept of quality.
Although frequently dated 1876, the contract was not let until March of 1877. A.S. Miller and Sons finished this, their most long-lived covered bridge, in November of that year. It was also one of the few bridges built by that firm which did not follow their usual Smith patent design. Plans in this case were by A.J. Cason, the local bridge superintendent.
In addition to Cason's strange truss, the bridge was immediately subject to protests from farmers complaining of the "low girts," which prevented passage of loaded hay wagons. Despite such disadvantages, or perhaps because of them, the bridge resisted every act of nature's destructive forces until 1947, when the old span was blown broadside into the Molalla River by a severe winter gale. Its passing was noted throughout the Willamette Valley for it had become a rural symbol of the settler's conquest over the rawness of the frontier.

Interesting add.

Does the Highway Commission categorize it as a Howe?
