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.


River flows are receding in the San Joaquin River and crews have been begun cleaning up previously flooded work areas. South of the river, construction continues on support piers and the pergola structure that will eventually carry trains over the existing freight line.


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