False Skew Arch 

Written by Peter Dispensa

A false skew arch is constructed similiar to regular masonry arch where the courses of stone are laid parallel to the abutments or springing line but the courses are shifted forward on one side of arch to create skew. The construction is different than a helicoidal skew arch where the masonry courses are diagonal to the abutment.

Amtrak Bridge
Posted February 8, 2012, by Bob Whitworth (go75 [at] cox [dot] net)

I used to live in Meriden, CT. As I recall, this bridge is historic in that it may have been the very first "skew arch" bridge in the United States, if not the world. Few people know of this obscure tidbit. Worth looking into.
