San Joaquin River Viaduct & Pergola

Overview

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.

Location

In north Fresno, parallel to SR 99 from the San Joaquin River to approximately Herndon Avenue.

Currently

At the northern end of the San Joaquin River Viaduct, girders have been set and a cast-in-place concrete arch is underway for the section that crosses over the river (previous page). Concrete is being poured for the deck segments on the north side of the river (above), while further south, crews continue constructing barrier and intrusion protection walls along the sides of the pergola section of the viaduct (below). 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.

Timeline

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