5: Custom helix support over return loop. A Central Valley through truss bridge was placed over Spavinaw Creek, north of Siloam Springs. The model bridge was constructed 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 prototype 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 establishing era and locale. The upper bridge over Spavinaw Creek will be created using five Micro-Engineering deck girder sections (9). MRH-Jan 2013
