Fortunately, it's not as heavily traveled as an Interstate Hwy bridge, but it may be even more vulnerable because it's huge concrete bearing pillars were designed to be standing in water like a Lake Auburn behind an Auburn Dam!!! (America's biggest monument to stupidity by remaining unfinished at the hands of Demonicrats and gutless Repellicans!)
Now they've been standing there in the direct burning sunlight for nearly 40 years!!!
I just flew over it in the old motorhome with my grandkids aboard on the way to Sugarpine Reservoir! What a thrill!! Now I gots "bridge-a-phobia" to go along with my acraphobia!!!
