California High-Speed Rail (CHSR)

Project Stats


The California High-Speed Rail (CHSR) is a publicly-funded rail system under construction in California. Upon completion, it will connect the Anaheim Regional Transportation Intermodal Center in Anaheim and Union Station in Los Angeles with the Salesforce Transit Center in San Francisco via California’s Central Valley.

Passengers will enjoy “one-seat” travel between these points in 2 hours and 40 minutes, a distance of 380 miles on trains that reach up to 220 miles per hour. Future extensions to San Diego County and Sacramento are also being developed.

This ambitious project is being managed by California High-Speed Rail Authority (CHSRA). In August 2013, the CHSRA broke ground on CP1, a 32-mile portion of the project that stretched from Avenue 17 north of Madera to East American Avenue south of Fresno.

The Project

CP1 is a multi-faceted project that includes the following: 

  • 12 roadway/railroad grade separations
  • One tunnel 
  • Two mainline viaducts 
  • Two trench sections
  • Utility relocations 
  • Existing railroads track realignments
  • Roadway relocation
  • One river crossing over the San Joaquin River

In total, the construction of 33 structures and 32 miles of guideway were required to complete this phase of the high-speed railway project.

In 2013, the award-winning California construction firm Tutor Perini Corporation (as a joint venture with other firms) was awarded the contract to build CP1 after a lengthy bidding process. The company’s commitment to large and complex civil, building, and specialty construction success necessitated working with the right partners to help fulfill the demanding needs of CP1. MSL was excited to be hired by Tutor Perini to provide construction support for this project.

MSL’s Approach

We brought our whole team of rebar detailers, engineers, and installers on board to help facilitate our client’s needs. This included close collaboration with all stakeholders through the scheduling, detailing, logistics, and installation phases. 

MSL partnerships are always for the long haul, with our team available for questions and meetings at or between every stop along the way. Our approach ensures complete transparency and open communication between all stakeholders and our experienced detailers, fabricators, engineers, and installers.

 At MSL, we prioritize delivering quality, durable work on time, and exceptional client service. We believe these values are what our clients value most.

The Results

As of summer 2022, MSL has installed more than 40,000 tons of concrete and steel, with nearly half of the required structures complete. Work is on schedule to be finished in 2023, completely aligned with the project’s timetable. 

Our entire team is committed to this project through to its final stop of bringing faster, safer, and more reliable interstate travel to residents and visitors to the Golden State.
