Now that I had the Car Float<\/a> the next thing to add was the Transfer Bridge that connects the car floats to the terminal. <\/p>\n\n\n\n

The transfer bridge I’ll model is the replacement thru truss bridge that was put in place in 1920. As its predecessor, it is made of timber and consists of three framed Howe trusses. The available plans give a good idea of its size (approximately 104′ length and 40′ width) and the few photos document on a sufficiently detail level (at least for N scale) the way it is built.<\/p>\n\n\n\n

I could not find any model that would come close so it was a no brainer to scratch-build the model and to stay as close to its prototype as possible. I had never before worked with laser cut wood structures so I gave it a try. I designed the structure with a vector graphics design tool (Inkscape). I would leave it up to the laser cutting service to deal with the intricate cutting. Following are the rough specifications of the transfer bridge project:<\/p>\n\n\n\n
