March 2013 (38.56667 Degrees, -120. 44242 Degrees) PiPi Bridges |
The wingwall on the north side of the Glenn Oviatt Bridge provides the bridge's construction date as 1998. A shear key on the seat-type abutment beside the wingwall looks like it was broken, perhaps due to a recent earthquake. There are normal faults all along the Sierras east of this bridge.
This completes our study of the bridges across the Middle Fork of the Cosumnes River. There were only five bridges across a fifty mile long river: the two bridges at Mt Aukum Road, the Rocky Bar Road Bridge which is difficult to cross because the road isn't maintained, and the two PiPi Bridges that are closed during the winter. Perhaps this is typical for bridges in mountainous regions?

Glenn Oviatt was a partner in an important sawmill in the area, it is supposed that his company trucks used the old bridge (east of the new span) to haul logs out of the forest and I imagine he was integral in getting the new bridge built. His sawmill in nearby Omo Ranch is no longer operational.
