U.S. 97: Greensprings and California Avenue Bridge Replacements - Work Schedule
The Greensprings (MP 275.8) and California Avenue (MP 274.7) Bridges on U.S. 97 will be reopened this December. Until then both work zones will remain open to through traffic but lane restrictions will continue to be needed. The restrictions apply seven days a week until project completion.
U.S 97 Greensprings Bridge – Traffic is limited to one lane in each direction over the Greensprings Bridge for the duration of the project. In order to keep U.S. 97 open, motorists will use one-half of the bridge while crews demolish and reconstruct the other half. Traffic is expected to be switched to the newly rebuilt half of the bridge before Memorial Day. Flaggers will be in place to help control traffic during the short lane closures required to make the switch. Reduced speeds of 45 MPH will be posted through the Greensprings Bridge work zone and strictly enforced.
U.S. 97 California Avenue Bridge – The currently operating one-lane, signalized detour bridge will stay in place through December. Sensors in the roadway will detect vehicle presence and adjust signal timing to allow for alternating lanes of through traffic. This system will ensure that vehicles moving through the detour have cleared the roadway before allowing traffic in the opposite direction. This signalized detour is similar to the one used at the same location several years ago when the bridge was repaired. The posted 35 MPH California Avenue Bridge work zone speed limit will be strictly enforced. Motorists are advised to expect delays of less than five minutes when traveling through this area.
Project Summary: U.S. 97: Greensprings and California Avenue Bridge Replacements
The U.S. 97 bridges over Greensprings Drive (MP 275.8 just south of the Klamath Falls city limits) and California Avenue (MP 274.7) have extensive cracking and have been rated in poor condition and in need of replacement. The existing bridges are being demolished and rebuilt into new structures. The new bridges are expected to open to traffic in December of this year.
The project is part of the Oregon Department of Transportation's 10-year, $3 billion Oregon Transportation Investment Act (OTIA) program. During the next decade, OTIA will repair or replace hundreds of bridges, pave and maintain city and county roads, improve and expand interchanges, add new capacity to Oregon's highway system, and remove freight bottlenecks statewide. About 18 family-wage jobs are sustained for every $1 million spent on transportation construction in Oregon. Each year during the OTIA program, construction projects will sustain about 5,000 family-wage jobs.
