NS/NW/Wabash Bridges over Mississippi River at Hannibal, MO

Wabash Mississippi River bridge at Hannibal, MO.
[Note the bins for the Bunge elevator under the lift span.]

On the west side, it crosses the BNSF/CB&Q tracks then goes through a river bluff tunnel to curve south. Evidently this lift bridge was moved from Florence, AL in 1993 to replace the original 1871 swing span. It doesn't look like it has a very high lift. Since tugs used since 1993 don't have the high smokestacks of the old steamships, maybe the Mississippi River no longer needs a high clearance. Although some historic steamboats are still run as cruise ships. So maybe this is higher than it looks. It is a 406' span. Maybe the length of the span makes the towers look shorter. Once stat I miss from Bridge Hunter is vertical clearance.

[You can see the boat up against the span to the right of the swing span. I wonder if the water appears rather high.]

Robert Andrews The swing span was replaced by a lift bridge in the 90's. Hannibal is also the home of the Wabash's only tunnel. A city park is on the bluff above the tunnel approach, diamond with the BNSF K-Line and the bridge approach. However, my last visit vegetation had taken over and all are hard to view from the "scenic lookout".

Robert Daly posted three photos with the comment: "More bridgework--the NS ex-Wabash bridge over the Mississippi at Hannibal, April 12 2013. The view through the woods shows the BNSF line from St Louis to Burlington crossing the NS. The NS enters a tunnel immediately after crossing the BNSF."

The last photo is looking down at the end of the bridge and the diamond from the trail. The Wabash crossed the CB&Q.

And the following post taught me that he is looking down because the Wabash route goes into a tunnel.
