|November 2012 (38.922 Degrees, -121.039 Degrees) Foresthill Bridge|
Continuing down the North Fork of the American River and back to the Foresthill Bridge. We can see the river (considerably diminished from the Ponderosa Way Bridge) on the right side of the above photo. According to the excellent website provided by Placer County and Quincy Engineering
, the seismic retrofit consists of strengthening or replacing the truss members and providing buckling restrained braces that act as dampers to absorb energy and reduce the superstructure movement during the Design Earthquake.
Other work includes improving access to the underside of the bridge, removing the lead-based paint and repainting the bridge, widening the deck, etc. All of the repairs and improvements should be completed by the end of the year.
