Connecting Communities

The Foothill Gold Line light rail transit (LRT) project in California’s Los Angeles County was the second of three planned segments of the Metro Gold Line light rail system. The second segment, from Pasadena to Azusa, extended light rail service 11.5 miles and added six new stations (Arcadia, Monrovia, Duarte, Irwindale, Azusa Downtown, APU/Citrus College). In a joint venture with Kiewit, known as the Foothill Transit Constructors, Parsons provided all architectural and engineering services during the construction phase. In addition, we were responsible for the related structures, systems, and facilities such as:

Service and inspection bay in main shop building

  • New bridges
  • Retaining walls
  • Sound walls
  • Improvements to existing bridge structures and drainage systems
  • Traction power elements
  • About 14 at-grade crossings with gate protection
  • An overhead contact system for the traction electrification system
  • An LRT control/signaling system
  • A freight signals system, and communications systems

We were also the lead designer of the Gold Line Operations Campus in Monrovia a 24-acre, full-service maintenance and operations facility constructed to the U.S. Green Building Council (USGBC) LEED Gold standards.

Since its completion, the Foothill Gold Line LRT system has improved commute times, traffic congestion, and reduced pollution by connecting important employment centers, dozens of universities and colleges, hospitals and research institutions, as well as several regional destinations that attract tens of thousands of visitors to the growing network of rail lines connecting all areas of the county.
