(c)2005 These three bridges are all for car traffic,...or were all for car traffic. The one in the middle you can see is being prepared to be removed. It was the first to be built. Several years later the bridge on the right was added. Then, just last year the bridge on the left was finished to replace the old bridge in the center. These three bridges link Interstate 80 from Crocket, California, in the foreground, to the City of Vallejo.
