The San Joaquin River Viaduct is an approximately 4,700-foot structure that will span the San Joaquin River in north Fresno and the Union Pacific tracks parallel to State Route 99. It will feature arches representing the northern gateway into Fresno, and a pergola structure to allow high speed trains to cross over the top of the Union Pacific tracks.
In north Fresno, parallel to SR 99 from the San Joaquin River to approximately Herndon Avenue.
At the San Joaquin River Viaduct, foundations have been poured for a cast-in-place concrete arch that will act as the high-speed rail “gateway to Fresno County.” Nearby, a worker uses a high-pressure hose to blow debris out of the rebar in preparation for another concrete structure pour. The completed viaduct, nearly a mile in length, will be one of the largest structures on this first phase of the high-speed rail project.
