San Joaquin River Viaduct

[1] The 4,741-foot (1,445 m) bridge combines a double concrete arch span crossing the river with a pergola structure to carry the high-speed tracks over Union Pacific Railroad Fresno Subdivision tracks.

[2][3][4] The river crossing is immediately upstream of the Union Pacific and California State Route 99 bridges.

[2] The bridge is part of CAHSR's Construction Package 1, the contract for which was awarded in August 2013.

[2][3] By February 2019, crews were working over the San Joaquin River and making final preparations before placing concrete at the east archway of the viaduct.

The concrete placement was while crews continued forming up the west archway and building an additional scaffold.
