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.


Crews begin construction of the signature "gateway arch" on the San Joaquin River Viaduct. This structure is the first step in constructing the falsework for the arch that will mark the border of Madera and Fresno counties. A crane lifts the framework and slowly lowers it into place, guided by workers who then bolt it into position.
