John Alexander Lower Waddell a lift bridge engineer specializes in vertical lift bridges also designs bascule bridges with his partner John L Harrington, the opposite is Joseph Baermann Strauss who specializes in designing bascule bridges but design vertical and direct lift bridges. This bridge is a Waddell & Harrington type, and if you look at Nathan Holth's page of the Morgan Murray lift bridge you will see the design plan of this particular bascule bridge with a fixed bridge approach.

Hey Nathan

Your page of the Morgan Murray bridge has a design planned bascule bridge with the fixed bridge approach. They must of decided to build a vertical lift bridge instead in Tacoma Washington then use the design to build this one here.
