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.


At the San Joaquin River Viaduct alongside State Route 99, crews are excavating at the north bank of the river, preparing to construct more support piers for the foundation of the viaduct. Meanwhile, on the south side of the river, other crews are constructing piers and an abutment. Guideway clearing between the San Joaquin River Viaduct and Avenue 7 has also begun.


This project began in the summer of 2016 and is expected to take approximately three years to complete.
