San Joaquin River Viaduct & Pergola


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.


Work is underway on the signature arches that will serve as the high-speed rail “gateway” to Fresno and Madera counties. Falsework has been constructed on either side of the structure to form the arches that will be filled with concrete. Nearby, another crew is tying rebar for barrier walls along the sides of the structure. 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.
