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.
In north Fresno, crews are working over the San Joaquin River and making final preparations before placing concrete at the east archway of the viaduct. The concrete placement is planned for next week while crews continue forming up the west archway and building an additional scaffold. These arches will act as a suspension bridge support for the bridge span over the river.
