This bridge is a transition design because it has both pin and rivet plate connectons.
pin-connected bridge. And the eyebars exist after the 2005 rehabilitation. Like the ABS Bridge in Kansas City, this bridge has an unusual lift design. But the bridge was made movable not because of navigation, but because of floods. More on that below. Each level has two tracks. Originally, the upper viaduct was used for passenger trains and the lower viaduct carried freight trains. [Engineering News-record, Volume 77]


This Kansas City Terminal Railway (KCT) Bridge was brought to my attention by a copyrighted photo that includes an interlocking tower.
ATSF 946 East, a loaded "UCEX" Unit Coal is led across the KCT Kansas (Kaw) River bridge from Kansas City, KS into Kansas City, MO behind an ATSF C41-8W, an SP SD40M-2 and an SD45T-2R on August 25, 1994. The KCT-owned bridge carries double tracks on two separate levels and is one of, if not the busiest rail bridges in the Kansas City area, in use by every railroad passing through KC. This would be one of the last photos I took before moving away from the Midwest to Virginia for a new job in September, 1994. Photo © Glenn Anderson 2018

Give them a warm welcome into your community! Dennis DeBruler, I think that is State Line Tower. The state line runs literally a few feet east of the tower.

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 systems. "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]


Comment by Greg in Bridge Hunter
Historic Bridges explains that the new double-deck spans were built around earlier spans to reduce the interruption of train traffic.
