Sonoma County, California Bridges: U.S 101 Bridges across the Petaluma River

August 2014 (38.22833, -122.61528 Degrees) U.S. 101 Bridges

It took me a while to figure out what was happening on today's structure, the U.S. 101 Bridges (20 0154L/R) across the Petaluma River. I believe the existing bridges (supported on single column bents) are being replaced by a new bridge (on shorter three column bents).We can see the I girders being placed on the new bent cap. After they put traffic on these new girders they'll start to remove the old (1955) bridges.
