KAHLOTUS, Wash. – Lower Monumental Lock and Dam will close to public vehicle traffic across the dam Oct. 17-28, operations officials with the U.S. Army Corps of Engineers Walla Walla District, announced today.
The temporary traffic-crossing closure is necessary to ensure public safety while work is conducted from the top deck of the dam to install trolley pipes to hold fish-tracking equipment on the powerhouse and spillway. This work requires the use of cranes, divers and additional equipment that will block the deck, according to officials at the dam, located at Snake River Mile 41.6 near Kahlotus, Wash.
Travelers can call 1-888-DAM-INFO (1-888-326-4636) for the most current dam-crossing information at all three of Walla Walla District’s dams that allow public traffic to cross the Snake River: Lower Monumental, Little Goose, near Starbuck, Wash., and Lower Granite, near Pomeroy, Wash.
