698:. A 2002 study showed that water begins to flow from the Sacramento into the Fremont Weir when the flow reaches approximately 2,000 cubic metres per second (4,200,000 cu ft/min); for comparison, the capacity of the Yolo Bypass is 14,000 to 15,000 cubic metres per second (30,000,000 to 32,000,000 cu ft/min).

The original Yolo
Causeway opened on March 18, 1916 as a two-lane structure 21 feet (6.4 m) wide and 16,538 feet (5,041 m; 3.1322 mi) long, connecting what is now the city of West Sacramento with Davis, California. Residents celebrated with the three day-long Causeway Celebration, held

Initially, the causeway was composed of a timber trestle section (2,470 ft or 750 m long on the west) and a concrete trestle section (remaining length), with a 113-foot (34 m) plate girder bascule span, which was opened to permit passage of levee maintenance barges. The causeway width

The current causeway was built in 1962. From west to east, the causeway is composed of twinned 2,880-foot-long (880 m) concrete trestles, a 4,700-foot-long (1,400 m) earth fill segment, and twinned 8,800-foot-long (2,700 m) concrete trestles. The easternmost of the two bridges is the
