I stand corrected. Now we know that A-frame portal bracing was in use by 1889.

David Hammond might have something to say about the comments below! Here is an 1889 A-Frame portal by Wrought Iron Bridge Company. http://www.historicbridges.org/pennsylvania/dewey/index.htm

This was an early Indiana Bridge Company design that featured an open letter plaque. There used to be one just like it in my home county and I believe it was built in 1892. IBCo was always very innovative, so it would not surprise me if they developed the A-frame portal.

If the 1891 date is accurate, then this would be the oldest bridge that I have seen which features A-frame portal bracing. Prior to viewing this page, the oldest A-frame portal bracing that I had encountered was on an 1895 double-intersectional Warren truss.
