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

Plenty of changes are happening at the Fresno Trench and in the median of State Route 180 (SR 180). Crews are currently constructing the concrete caps for piles that have been drilled into the ground next to the Union Pacific tracks that will make up a barrier wall for the trench, which is designed to cross under a rail spur, a canal and the highway. Other workers have excavated up to the canal and underneath a temporary extension of westbound SR 180, and are working on the retaining walls that will make up the sides of the high-speed rail crossing under the highway.

Timeline

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