Foothill Gold Line

About Us

The Construction Authority is a single-purpose agency, put in place by the California State Legislature in the late 1990s to plan, design, and construct the Gold Line light rail system from Los Angeles Union Station to Claremont (later extended to Montclair). Los Angeles County Metro is the Transportation Authority for the County of Los Angeles and is responsible for operating and maintaining the Gold Line and other rail and bus systems throughout the county.

The Construction Authority has already built two of the three Gold Line segments; Union Station to Pasadena and Pasadena to Azusa; and is currently underway on the third segment from Glendora to Montclair. Once the Construction Authority has completed construction and testing of each Gold Line segment, the agency turns that segment over to Los Angeles County Metro to operate. Metro is then the responsible agency in perpetuity.
