Size:Over 10' long.
CMR built an HO scale automobile bridge for a private customer based upon the Queensboro Bridge in New York.
It features approach bridges,a five foot long suspension bridge and a three foot long truss bridge. There
are over ten thousand parts drawn, cut, assembled and painted by the CMR staff. The bridge is crowned by
yellow LEDs and the towers have blinking red LEDs. Light poles along the sidewalks were added later.
Finished photos are at the top with production photos below.

The finished bridge ready to install on the clients layout.
Note the stone piers with decorative towers that support the bridge.
The bridge features steel straps rather than cables, each one is five seperate peices with rods spacing them aparts.
The bridge supports and truss construction is boxed with wires running up inside them to the LEDs along the top.

The bridge gets very complicated in places with lots of angles and parts. Final paintng and weathering
is done by hand and with an airbrush.
This pier features a skewed arch to allow for an angled track to run thru it.

Note the lights running along the top of the bridge.
Detail of the skewed center pier that will have a track running through it.
This is the center cross bracing for one of the main bridge towers.
The bridge tower starts to take shape. It is constructed of acrylic and styrene pieces.
One of the main bridge towers. It will still get some decorative elements added to it.
The tower has more than 65 pieces alone.
This is a study model to figure out how we are going to build the suspension part
of the bridge. Many parts will be revised and a cleaner version will be built before
proceeding with the final model.
Another view of the study model. Yes that is a lot of parts!
Most of the model has been worked out and we are working on the walkway.

This is an approach bridge. It measures 28" long and is in the same construction style
as the suspension bridge. There are over 550 parts to this bridge alone! Note the very
nice bridge pier as well.
Socket wiring for street lights. The brass rods run the length of the bridge.
Ramp and approach bridge with piers dodging tracks and streets below.
This is the far end of the bridge. The towers still get a top on them and a lot more detail.
There will be two towers on eihter side of the column. Access to the pedestrian walkway is via
the towers. Towers will be located at other locations as well.
There will be a tunnel portal at the bottom of the ramp, it will have an arch like the
columns and a tower on either side of it.
Lights! Eighty two LEDs light up the top of the bridge.
Each one is wired down thru the bridge with tiney 24 gauge wire and a resisitor.
THe bridge is finally painted and weathered. Just a little rust and some chalking of the paint.
