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.
Crews are installing metal decking over the river, forming the floor of the San Joaquin River Viaduct. Once concrete has been poured to form the deck, work will begin on the signature arches that will serve as the “gateway” to Fresno County. 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.
