Getting Real column - 3
A Central Valley through truss bridge was placed over Spavinaw
Creek, north of Siloam Springs. The model bridge was con-
structed for a different application. If you look carefully, you’ll
see that the photograph of the actual bridge shows two short
through truss spans. The Central Valley bridge will be cut and
adapted to match this configuration (7).
Figure 8 is a closer view of the Grandview bridge. The proto-
type featured a great Southern Belle sign on the bridge. One of
the reasons for modeling the bridge here in the first place is to
provide a location for that sign! It is an excellent way of estab-
lishing era and locale.
The upper bridge over Spavinaw Creek will be created using
five Micro-Engineering deck girder sections (9).
