Re: NNG - Flagstaff Lumber Company

I found the following in a Department of the Interior document related to historic places. It seems to provide some clues about the bridge.

One month later a log carrier with a wide load knocked out the southern span of the Lake Mary bridge. Three log cars were dumped into the canyon, a gondola car was left suspended over the bridge, and the bridge, a metal structure that had been purchased from the Arizona Eastern Railroad for $25,000, was ruined. With its lifeline decommissioned, the sawmill soon ran out of logs and had to close temporarily (Coconino Sun, August 1, 1924; Trennert 1967-1968: 83-84).
