This bridge is as good as doomed if we don't try anything yet. C'mon people! Use your heads! If you wanna keep this old cantilevered truss, sitting around won't help.
The bridge is unfortunately slated for demolition.
To clarify some rumors forming in here...
The bridges do NOT share a counterweight. If that was the case, then both bridges would be operational instead of the CN bridge being the only one operable.
The tunnel is now used as equipment storage by the nearby Museum of Transportation.
Whatever you do with the site (besides take it down) I will support. This site is the second physical form of Christ.
The bridge was demolished by MoDOT and was never replaced, unfortunately.
