Bundy Bridge in Pompey's Pillar, MT
Posted September 11, 2012, by Angela Fares (Angela [dot] Fares [at] bnsf [dot] com)

Dear Mr. James McCray

I absolutely love your website, but wanted to offer one slight correction in order to give credit where credit is due. Bundy Bridge near Pompey's Pillar, MT was definitely the first Warren through truss bridge to span the Yellowstone River in Montana, however the very first Warren through truss bridge in the great State of Montana was actually constructed in 1895 across the Big Hole River near Glen in Madison County. It was 90 feet long and located on a road that once connected Dillon, a railroad station and county seat of Beaverhead County with the Ruby River valley in southwestern Montana. However, the Bundy Bridge is an exceptionally rare example of a bridge built by a private construction firm without the direct involvement of the Montana Highway Commission which, beginning around 1916 or so, began to adopt the Warren truss through bridge model as a standard for railroads. In mid-1882, the Northern Pacific Railway (one of our predecessor railways) had reached Pompey's Pillar and established a station half of a mile south of the landmark on the Crow Reservation (it was subsequently moved two miles east of Pompey's Pillar in 1905). The "new" bridge in 1915 was an important part of our early history and was the first bridge of its kind to cross the Yellowstone River in Montana, but I'm afraid we must credit the bridge in Madison County with the honor of being the first of its kind in the great State of Montana.

Keep up the great work! I shall bookmark your site with great pleasure and look forward to visiting in the future! Your photographs are quite lovely.

Warmest regards,

Very unique diagonals on this bridge composed of 4 angles laced together to form a box. It appears the Toston Bridge may have them as well.
