1905 BNSF/NP Bridge over Missouri River at Bismark, ND

(Bridge Hunter; no Historic Bridges; John Weeks III3D Satellite)

"Built 1905, reusing the piers from an 1882 bridge." [Bridge Hunter]

BNSF is going to build a new bridge. It wants to replace this one. Some citizens want the new bridge to be on a new alignment so that this bridge can become a trail.

I was surprised the Missouri is so wide this far north.

Rich Wallace There is a theory that when you leave a location, the train will come. Seems to have been my experience when I have seen others shots who were also at that location. Now I try to get them to leave. Ha!
Dennis DeBruler I was at Union Depot in Joliet to meet my uncle and his railfan friends. BNSF was dead. I kidded them that I'd go check out Brandon Lock so that the trains would start coming. Sure enough, they did come after I left.

Well I got my shot at the Missouri River bridge this morning. But the clear blue skies were gone replaced by bright overcast. Instead of going straight to the bridge I went down into Mandan to see if anything was there ready to go east. I should have done that yesterday! But while driving there I heard the dispatcher on my scanner talking to a westbound already west of Mandan saying they'd be meeting two eastbounds at Lyons. Ah, there were two coming at least. But checking Mandan I found there was already an eastbound autorack train here and figuring it would have to leave before the other two eastbounds arrived I had better get up to the bridge now. Arrived at the bluff and back to my spot from yesterday, set up the camcorder, and horns blowing from the west. It was almost here! Single SD70ACe up front of the long autorack and no DPU on the rear. Not sunny but at least I got something. It was 80 and rather humid too.
Paul Birkholz Perhaps empties going to storage with just one unit?
Richard Olson Nice, and the autoracks help keep your eye following the train beyond the bridge.
Brian Ambrose Good point. Coal hoppers or grain cars would not have had the same effect.
These 1882 piers are made with granite. The spans were built in 1905. [John Weeks III]

Brian Ambrose And this is the second train of the morning approaching the bridge from down below along a walking trail. Now it is raining, and 78 humid degrees.
Jim Weisenbach Icky weather... sounds like 'home' (NJ)
Dennis DeBruler A nice view of the ice breaker on the pier.
Maybe BNSF would be better off moving the new bridge to a new alignment.
Based on a paper written by Ed Murphy of the ND Geological Survey, the railroad (first Northern Pacific, and now BNSF), have had endless problems with the eastern pier of the High Bridge. Just after completion, the east pier began shifting towards the Missouri River at a rate of 3 to 3-1/2 inches per year. A number of repairs were attempted, but none seemed to work. In 1898, the pier was dug out and moved back onto a larger foundation. By 1902, the pier was already 4 inches off center. After further investigation, it was suspected that the city water reservoir located on a hill above the railroad track was leaking large amounts of water, causing the entire hillside to slide towards the river. The NP built a tunnel under the area to try to drain the water, but the pier continued to move. More projects were completed in 1918, 1923, and 1940 to try to slow down the landslide. In 1951, the NP undertook a major project to cut down the hill and regrade the area. This helped the situation by slowing down the movement to 1/3 of an inch per year, but did not stop the movement. [John Weeks III]
According to John Weeks, BNSF runs most of their trains over the former GN route. This NP route became busy hauling Powder River Basin Coal. But that traffic is drying up as coal-fired power plants are being converted to gas or shuttered. So the cost of stopping traffic on this route while they replace the bridge might not be high enough to help save the old bridge with a new alignment.
