The next task in creating the span was the girders that support the deck. Plastruct, Evergreen and the like produce nothing at all large enough for these so I bought large plastic strips from a hardware store and then added styrene strips to create the I beam profile. A total of eight of these were produced then super glued strait onto the underside of the deck. I did wonder if there would be trouble with them coming off with the least knock to the span but they've proved to be very durable.

With the beams all in place some plates were added where the bearings will sit on top of the legs. On top of the road deck strips of cork underlay were put down to create the foot paths and central reservation. With all major structural elements now firmly in place the whole thing got painted. The grey was from the same rattle can I did the legs with, the roadway and girders brush painted with appropriate colours.
