Also take a look at the footings - the are angled towards the center to take the compression loads from the bottom members.

This bridge was still standing in late June of 2017, although part of the timber approach is collapsing. I'll post my photos of it in the near future.

I'm not sure that this is the last simple truss built for a railroad at a new location. The Washington Blvd Bridge in Los Angeles County is a simple Pratt truss, and it was built in 2001 as part of a track re-alignment, so there was no bridge at the location previously.

Great photos, Craig! How did you get to the bridge - I wasn't sure if any of those roads were open to the public?

Posted April 11, 2013

It's good to see a city take pride in a historic bridge and go to such efforts to preserve it.

Posted February 27, 2013

Is this the only wooden through Howe truss still around? (Not counting covered bridges, of course.)

Posted January 26, 2013

I know of at least one lost bridge that has a Street View image but no actual photos. If Google heads down this street again, the image will be lost. I have seen other websites save a static copy of the Street View image to protect against this. Perhaps that is worth doing here as well?

Posted September 18, 2012

I'm not sure about the 1901 date. One of the two short spans has a "1921" plate.
