The Oregon Department of Transportation will begin work next month to replace three Umatilla County bridges.
The three sites are Goose Rock Bridge, on Highway 19 west of Dayville; Camas Creek Bridge, on Highway 395 south of Ukiah; and North Fork John Day Bridge, on Highway 395 at the Umatilla-Grant county border.
During construction, temporary traffic signals will control alternating one-way traffic across the bridges. The travel lane will be 16 feet wide, and no oversized loads will be allowed to cross, according to ODOT.
The bridge replacements are part of ODOT's 10-year, $3 billion Oregon Transportation Investment Act program, which aims to improve hundreds of bridges, roads and highways across Oregon.
The Umatilla County projects will cost a total of $21.9 million, at close to $7 million each. Work begins April 6, and each is expected to be completed in 2011.
