Concrete The amount of concrete used in the bridge foundation (1,900 cubic yards) is equivalent to the amount needed to complete foundations for 43 homes. It took 6.27 million cubic yards of concrete to make Shasta Dam and 16,000 cubic yards for the base of the TransAmerica Tower. Weight The Space Needle weighs 3,700 tons — more than twice as much as the 1,600-ton Calatrava Bridge. The Eiffel Tower weighs 7,000 tons and the Golden Gate Bridge is 419,800 tons.
	Cables The superstructure is made of enough cable to stretch across more than 14 football fields. Pre-fabrication Due to the sensitivity of the riparian site, steel for the bridge is being pre-fabricated at USI, a steel yard in Vancouver, Washington. A total of 18, 40-foot deck sections and 25 truck loads of pylon pieces were transported from Vancouver to Turtle Bay. Fourteen large pieces were shipped by barge to Vallejo and then trucked to Redding, sometimes taking up the entire freeway. The trucks traveled at night and during the weekends to avoid significant traffic delays. The effort required the coordination of three state Highway Patrol agencies.
