Folsom Dam Bridge
The original plan to raise Folsom Dam included the construction of a $36 million temporary vehicle bridge to provide a detour for traffic that normally uses the Folsom Dam Road to cross the American River. (For national security reasons, the road over the dam is currently closed indefinitely.)

When Congress authorized the Corps to raise Folsom Dam in 2004, it directed that the bridge be permanent and authorized the additional $30 million needed for a permanent span.

The location of the bridge and its connecting road alignments are currently under study. It will take a number of years to complete these studies as well as the actual design and construction of the bridge and connecting roadways.

  • Start construction - expected May 06
