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.
