Fresno Trench Banner

WHAT:

An approximately 2 mile trench is being built starting between Olive and Belmont Avenues and running to Stanislaus Street in downtown Fresno. Work has begun in an area located near Thorne and H Streets.

Crews will also construct an underground crossing that will travel under State Route 180 as well as the San Joaquin Railroad and Union Pacific tracks and Dry Creek Canal.


WHY:

The trench will allow high-speed trains to pass underneath SR180 and avoid an at-grade crossing.


PROJECT SCOPE:

  • This will be the first section of the alignment to go below grade
  • The trench will reach a depth of approximately 40 feet
  • The construction at SR 180 will be a top-down project, meaning crews will dig from the top of SR 180 to a depth of approximately 80 feet, construct a portion of the tunnel and then reconstruct the highway.
  • The SR 180 work will require lanes shifting (first to the inside, then to the outside) but will not require any lane closures.

TIMELINE:

Work is currently underway on the trench section. Construction on SR 180 is expected to begin in late February or early March.
