The original Yolo Causeway opened on 18 March 1916 as a two-lane structure 21 feet (6.4 m) wide and 16,538 feet (5,041 m) long, connecting what is now the city of West Sacramento with Davis, California.
Residents celebrated with the four day-long Causeway Celebration, held from May 11–14, 1916.

Initially, the causeway was composed of a timber trestle section (2,470-foot (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 was doubled in 1933 when a new all-timber viaduct was added just south of the 1916 reinforced concrete structure; lights were added in 1950.

The Lincoln Highway association initially declined to shift its route to take advantage of the Yolo Causeway, but in 1928, following the completion of the Carquinez Bridge, it was made a part of the re-routed Lincoln Highway, the first road across America.
Later, the causeway became a part of US Highways 40 and 99W.
