March 2013 (38.49477 Degrees, -121.08421 Degrees) Cosumnes River Bridge |
The trick to building timber structures is to provide well-designed connections. The steel plate connectors look like they were manufactured especially for this bridge. Also, the trusses use diagonal steel rods at the top and bottom chords instead of the usual sway bracing.
There are several websites that discuss this unusual structural including StructureMag which has some nice construction photos and the section properties of most of the bridge members.
