The Foothill Gold Line Construction Authority (also known as the Metro Gold Line Foothill Extension Construction Authority) is an independent transportation planning, design and construction agency created in 1998 by the California State Legislature, SB 1847 (later updated in 2011-AB706 and 2012-AB1600). The agency was created to immediately resume design, contracting and construction of the Los Angeles to Pasadena Metro Gold Line (formerly the Pasadena Blue Line) which had been suspended by the Los Angeles County Metropolitan Transportation Authority (Metro) earlier that same year.

The newly formed Construction Authority completed the Los Angeles to Pasadena segment in just under three years, and the 13.7-mile line opened in 2003 on time and under budget.

The same legislation that created the Construction Authority also dictated its role to plan and construct any “fixed mass transit guide way eastward to Claremont.” The planning for the line was later extended to terminate at Montclair’s Transcenter, a regional transit hub for numerous bus and rail operations serving San Bernardino County and the Inland Empire.

Once construction is complete, the Construction Authority transfers the project to Metro to operate. This relationship is formalized in a Master Cooperative Agreement approved by both agencies’ boards of directors. The current Master Cooperative Agreement, signed in July 2010, manages the relationship for planning and construction of the next two segments of the Foothill Gold Line from Pasadena to Azusa and Glendora to Montclair.

Project Funding

The Los Angeles to Pasadena segment was funded through Propositions A and C (state and local funding). These funds were already in place when the Construction Authority was established and took over construction of the project in 1998.

The Foothill Gold Line segments (Pasadena to Azusa & Glendora to Montclair) are estimated to cost nearly $2 billion.

In 2010, the boards of directors for the Construction Authority and Metro approved the Funding and Master Cooperative Agreements between the two agencies. This was a significant milestone for the project – laying out the framework and mechanisms for $810 million from Los Angeles County’s Measure R half-cent sales tax to be allocated to the project between 2010 and 2019, and also formalizing the roles and responsibilities of both agencies during design and construction of the project.

The majority of the $810 million was used to design, build and purchase equipment to operate the Foothill Gold Line from Pasadena to Azusa; however the residual funding not used is now being used to ready the segment from Glendora to Montclair for construction. The majority of the $1.2 billion needed to build the extension from Glendora to Montclair will come from the Los Angeles County Traffic Improvement Plan, a half-cent sales tax measure (Measure M) from Los Angeles County Metro that was approved by voters in the November 2016 election. Measure M includes construction funds to build the Foothill Gold Line to the county line in Claremont and fulfills Los Angeles County Metro’s commitment to complete the line as a top priority. The Foothill Gold Line is listed in the expenditure plan as one of the first projects to break ground under the ambitious Los Angeles County Traffic Improvement Plan that includes 40 major highway and transit projects county-wide over the next four decades.
