Art,

The biggest oddity is why they would reuse the two deck truss spans on this bridge. I know the two large through truss spans were sent to a branch line, and I assume the third deck truss also went somewhere else. But this was not a poor railroad, and it makes little sense to not use all new superstructures on a major crossing like this.

Situations like this make me wonder how much is really unknown with some of these railroad bridges. Railroads were very resourceful, and reused as much as they could.

These two bridges also probably use older parts. The Iowa bridge has plaques from 1899 on the approaches, but it could be reasonable that the trusses are older. The Clay County bridge is clearly something special. These trusses match designs of early 1880s deck trusses. Both being strengthened and using helper bents indicates this may be a very old bridge.

John,

This is really interesting! It would be neat to discover that there is more early material around - hiding in plain sight. I've seen Phoenix through trusses configured similarly.

Regards,

Art,

Yes thatís the span. Note the difference between it and the more modern deck truss spans. This also isnít the only CBQ deck truss which has been heavily reinforced with four truss lines, possibly indicating thereís other exceptionally old trusses still in service.

John,

Is that the one referred to as road span, seen in images 29-32?

Regards,

I recently learned from a historical survey of this bridge that the easternmost deck truss was built from two of the original 1880 deck trusses, which were combined in 1903 to make a single span. This is a very unique and creative reuse of the old bridge spans.

A new railroad bridge is planned at this location but according the Army Corp, the existing historic bridge will NOT be demolished as part of the project. See attached public notice.

The railroad bridge was completed in 1880 by Chief Engineer George Morrison and the span was rebuilt in 1902. The adjacent automobile bridge was completed in 1935.
