Excerpt from the NP bridge book covering this line:
Bridge Number 117 was formerly known as Bridge Number 11.3, and was located 2919 feet beyond milepost 117. It spanned a ravine and had 27 bents in it's framed timber trestle. It was 426 feet long and 48 feet high at the deepest point of the ravine. While the vintage photos are from 1924, the bridge book shows the bents were renewed in 1935 and stringers in 1931, likely in anticipation of the cement traffic for Grand Coulee Dam that would take this route. The bridge was on a tangent and was on a .5% grade. The bridge book excerpt was from 1955, so it states this section of line was not in service. The trestle plan the bridge was built to was R-11-2C, which I have not found yet.
