8 bridges for the Columbia & Western

Clinician:

The CPR's Boundary subdivision is notable for having nearly a mile of bridges. The clinic describes how models of 8 of these bridges were researched, designed and constructed in a variety of materials from styrene to etched brass. Focus will be placed on selective compression, model design for strength, piers and abutments, painting, and designing bench work to allow easy installation many years later. A video run-by across all the bridges will end the seminar.
