The corps will be blasting as it lays the groundwork to connect the American River with the new dam.
Chris Gray with the Army Corps says Folsom Lake Crossing Bridge will be closed from 1:30 to 2:30 in the afternoon for the next two weeks.
"We've more or less excavated the chute that's part of the new spillway," says Gray. "That's where the water will go when it leaves the new dam and connects to the American River. So that's excavation's done. Right now, we're basically building that second dam."
Gray says the construction schedule calls for the dam to be completed in 2015. The connection between the lake and the spillway and the completion of the downstream chute is scheduled to be completed by 2017.
