I agree Art... They were kinda cool and I suspect there were many more spans (especially those located within towns and cities) that originally had them. Of course they would have been laid on top of a sub-flooring which was most likely wood, and this added additional weight to the whole. Moisture might have been a problem between the layers on this bridge and may well have been what was causing the cupping.

Tony,

I thought the bricks were a nice period touch. The Mead Avenue Bridge in Meadville, PA had them in 1918 (and possibly earlier).

I suspect it may have been more common than we think.

Glad to hear the repairs have been made though.

Regards,

Art S.

Looks as though the brick floor went by the wayside... Not a total surprise. It was unique but the last time I was there it was starting to sag where the tire tracks were. Hopefully they performed any other needed repairs to the floor beams and stringers while they were accessible.

And now they need to top it off with a better paint job! The last one looked good for a short time and then just looked shabby!

Thanks for the new pictures Mike! How does the recent work look in person?

This map shows the interurban (Ohio Electric) crossing at Main Street, so I'd assume that there were two bridges..

I found several cards from Eaton, OH with an identical bridge next to a trolley bridge over Seven Mile Creek but they are labeled Main St. Are the cards mislabeled or was there a sister to this bridge on Main St. or was the Main St. bridge moved here at some point?

Hmmmm.....

Whipple? No. I'd call it a Pratt.

We need a category for a herringbone brickwork deck as well.

Had a very nice paint job on it not too many years ago... But it sure didn't hold up very well.

There wasn't a lot of traffic when I was there 7/16/12. Got some nice shots.

What seems odd to me every time I see this bridge is the brick floor. I don't think I've seen that elsewhere.

Stopped today (28 January 2011)and grabbed a quick shot of this brige. I was surprised at how busy the street was so I only got one. I will post it later but it's still there.
