Rock-Blasting Project in Folsom Leads to Road Closures

FOLSOM -- The Army Corps of Engineers are asking area residents who use the Folsom Dam Crossing Road to have patience during one more round of road closures that could go on periodically until the end of September.

The massive emergency spillway project which allows excess water to be released from Folsom Reservoir to prevent a flood requires the use of explosives to clear rock formations.

“Removing some of the native rock from the end of the spillway so we can create a channel for the water to move from the spillway into the American River," Army Corps Public Affairs Specialist Rick Brown said.

The blasting will only take place between 7 p.m. and 8 p.m. beginning Monday and going through Sept. 30. Morning and midday hours were considered, but the evening hours were deemed to have the least impact on traffic. Bicycle traffic on the adjacent bike trail will be closed beginning at 6:30 p.m.

There will be a series of warnings sounded by horns 5 minutes and 1 minute before the charges are set off. An all clear horn will be sounded when the blast is completed.

The good news is that the road closure may not occur each night.

“We’ll do some blasting tonight, do some evaluation and remove rubble and see if we have to do anymore blasting, so it’s not necessarily everyday," Brown said.

Local residents seemed to take note of the notices and warning signs put up by the Corps, but they also say some will undoubtedly be caught off guard or forget. They say there is a possibility of traffic congestion during that hour as motorists and bicyclists scramble to divert around the closure.

Still walkers like Stephanie McDowell believe things will run smoothly. There was a previous period of closures for blasting in June.

"It's good to let people know what's happening and to be aware and that they close to road for a very short period of time," said McDowell.
