There are also two articles on my blog that are worth reviewing (first article and second article).
The irony of my designing this bridge is my total lack of an N-Scale Model Railroad Layout! That has not stopped me from enjoying the project though and hope to see others build the bridge and put it to use. One person is doing so and has shared this gallery of photographs from his build. They are all worth a look but the ones that are most salient will be linked into the appropriate page of this Instructable.
In no particular order relative to the photograph here are the tools that you will be needing:
