Dennis DeBruler, I think that is State Line Tower. The state line runs literally a few feet east of the tower. Here's the https://www.google.com/maps/@39.0825096,-94.6075911,134m/data=!3m1!1e3

I've seen double-decker bridges before, but one of the decks would be used by a road. Both decks of this bridge have two tracks, and the bridge is used by every railroad that goes through Kansas City. It was built in 1917 and rehabilitated in 2005.

The rehabilitation made the bridge strong enough so that both tracks on the upper deck could be used at the same time and the speed limit raised from 10-15 mph to 40 mph. The vertical structures were added after the 1951 flood so that the three spans can be lifted when the Kansas River floods. [Bob Franke comment in Bridge Hunter]

I believe this bridge originally had a screw-jack lifting mechanism similar to Railroad Bridge 3 & 4. I vividly recall the installation of the hydraulic jacks in the early 60's. [Lift system was added in 1961 [wikimapia]]
Prior to the start of the 1993 flood, the hydraulics were in disrepair and evidently had not been tested for years. Rumor had it that it was cheaper for the railroad to pay the fine for not testing the mechanism than to disrupt traffic. There was a mad scramble to find parts and hydraulic fluid, and in the end, only 2 sections were lifted. For years, a large tree dangled from the span that didn't lift.
[Bill-KCKs comment in Bridge Hunter]

Different sources have different facts concerning the dates for the jack system(s). "In order to provide for potential flood events, this alteration was to add a lift system that made it possible to raise the truss spans by 10.5 feet during floods. It is assumed that this system was added after the 1951 flood as a screw jack system, but in 1963 a hydraulic jack system was installed." [Historic Bridges]
