El Dorado County, California Bridges: Mount Murphy Road Bridge across the South Fork of the American River (3)

January 2013 (38.8015 Degrees, -120.8906 Degrees) Mount Murphy Road Bridge
The UglyBridges Website reports that the Mount Murphy Road Bridge carried 1,050 vehicles a day with 10% truck traffic during the 2000 inspection. I would say that was a fair assessment based on the number of vehicles I had to get out of the way for during my visit. Fortunately, the speed limit is only 5 miles an hour, perhaps because of the number of pedestrians that also use the bridge.

In the photo we see that two axle vehicles are limited to 14 tons, three axle vehicles are 21 tons, and four axles are limited to 27 tons. That seems pretty good for this little bridge. I wonder if the approach spans or the main truss span limits the vehicle weight?
