Northwest Lake Bridge Reconstruction | Condit Dam , Washington

Removal of the Condit Dam on the White Salmon River in Washington required upgrading existing bridge piers to withstand millions of yards of silt and gravel that would be washed downstream. The project included construction of a work bridge, drilling four shafts in solid rock and installing 4- foot round columns and a cast-in-place 6-foot deep cross beam directly under the existing pier caps. Existing columns were sawcut and the existing piers were completely removed from underneath the new cross beam.
