Rick,
It looks like floods were the main culprit...to be honest, I'm kind of surprised it survived 1913!
Interestingly, the HAER report says the interurban company folded in 1920, yet the 1924 span incorporated interurban tracks. Apparently no one realized that the interurban era was done....my guess is the tracks on the 1924 bridge were never used.
The HAER report explains everything...
I've never come across anything about the short lifespan for this structure. Could increased traffic volume have necessitated a change in 1924?
Looks like an interurban used this bridge according to HAER.
Interesting portal shots! I can't say I've seen a bridge with triple portals like that before.
Paul,
I was likewise surprised '13 didn't do it in. I would say it had a lot to do with the abutment damage that was described.
The situation with the tracks immediately made me think of Kellogg, with the plans for the IR&T that apparently never came to fruition.
