This is the 11,000th stimulus transportation project obligated nationwide.
The Spanish Creek Bridge replacement project on State Route 70, in Plumas County is financed primarily with $28.3 million by President Obama’s American Recovery and Reinvestment Act of 2009. The new 627-foot concrete arch bridge will be constructed approximately 40 feet west (down stream) of the existing steel truss bridge that was built in 1932. The new bridge will meet current standards including seismic, permit truckloads and 8-foot shoulders.
New Bridge features and facts:
- Only the fourth state highway concrete arch bridge built in California in the last 50 years.
- Capable of supporting up to a 150-axel oversized load and 360,000 lbs. The current structure supports 80,000 lbs.
- 75 year design life
- The 354 foot arch span will be one of the longest conventionally reinforced concrete spans in the state, rising 160 feet above the creek.
- The arches are 8 foot, square solid concrete at the base tapering towards the peak to give the bridge a slender arch profile.
- Construction will take 6,000 cubic yards of concrete and 1.7 million pounds of rebar reinforcement.
- A barrier railing design, modified to be bicycle friendly, is see through and beneficial for snow removal efforts.
- Installation of a 60 foot high concrete retaining wall with a natural rock appearance to blend with the surroundings will be constructed on the Chico side of the crossing.
The contract was awarded to CC Myers Incorporated, and is scheduled for completion in 2013.
