Fresno Trench & State Route 180 Passageway

Overview

A 2-mile trench through central Fresno, traveling under State Route 180 (SR 180), a railroad spur, and Dry Creek Canal. This will be the first section of the alignment to go below grade, to a depth of approximately 40 feet, as drilling rigs bore foundations for the trench barrier walls that will separate high-speed trains from the adjacent freight trains.

Location

From approximately Olive Avenue to Stanislaus Street. Work on the trench has begun south of Belmont Avenue along with excavation beneath SR 180.

Currently

Paving has been completed and traffic has been shifted to temporary outside lanes on State Route 180 (SR 180). Crews are currently at work in the median of the highway, pouring concrete for soldier pile walls on the section of the Fresno Trench that crosses under SR 180. The trench will take high-speed trains under a rail spur, a canal, and the highway, about 40 feet below ground level.

Timeline

Work began in July 2016 and will continue until late 2018.
