Major construction on an expansion of the LA Metro A Line is now completed on time and on budget, expanding the world’s longest light rail system from Glendora to Pomona.
The Foothill Gold Line extension, the $1.5 billion, 9.1-mile expansion project, includes four new stations and extends the line—formerly known as the Gold Line—into new areas of Los Angeles County.
The project, which began construction in July 2020, adds new stations in Glendora, San Dimas, La Verne and Pomona. It also includes the construction of 19 bridges, 21 street crossings, new parking facilities and more than 10 miles of sound walls — more than 548,000 recycled tires were used to mitigate noise near the rail corridor.
The line’s expansion was funded primarily by L.A. County’s Measure M half-cent sales tax, along with state grants and Measure R funds.
“Substantial completion,” a major project milestone, means all significant construction and system installations are finished, allowing the project to enter final testing, operator training and safety preparations before opening to the public.
