At the Fresno Trench, crews have broken through to the south side of State Route 180 and are excavating further underneath the highway. Excavation will continue until the trench is about 40 feet below existing ground level. When complete, the trench will cross under State Route 180, a rail spur and the Dry Creek Canal. The Dry Creek Canal phase 1 construction which involved re-lining sections of the canal is wrapping up in time for the irrigation season to begin. Construction has begun for the protective barrier that separates the high-speed rail alignment from the existing freight line that parallels the project. The barrier is 10 feet tall and will extend nearly 1,200 feet in this area of the project.
