Major construction is starting Friday on the Foothill Gold Line light rail project to add 9.1 miles of track and four stations from Glendora to Pomona.

The project is anticipated to be completed in 2025 and will add new stations to the Los Angeles County Metropolitan Transportation Authority's Gold Line system (now designated as the L Line) in the cities of Glendora, San Dimas, La Verne and Pomona, the Foothill Gold Line Construction Authority stated.

"The construction authority and design-build team have been hard at work for the past 10 months preparing for today's start of major construction," Foothill Gold Line Construction Authority Board Chairman and Pomona Mayor Tim Sandoval said. "There is a lot of work ahead to complete this project that is critically important to the region and to the corridor communities, and we thank our partners at the cities, LA Metro and others for the hundreds of hours they have put in to help us reach this milestone moment for the project."

If additional funding is secured by October 2021, the entire 12.3-mile project from Glendora to Montclair will be completed altogether by 2028, adding additional stations in Claremont and Montclair, the construction authority stated.

The major construction work is being carried out by the joint-venture team of Kiewit-Parsons, which was awarded the design-build contract in August.

This is the same team that successfully built the first two segments of the Foothill Gold Line from Los Angeles to Pasadena, and Pasadena to Azusa, both completed on time and under budget in 2003 and 2015, respectively, according to the construction authority.

The Foothill Gold Line from Glendora to Pomona is being built within an existing rail corridor that is shared with BNSF freight service.

Over the next five years, crews will relocate within the shared rail corridor more than nine miles of freight track, install two sets of light-rail tracks and build four new light-rail stations with unique artwork created by city-selected station artists, the construction authority stated.

The project will also rebuild 21 at-grade street crossings, build or renovate 19 bridge structures, relocate underground utilities, install new communications systems and make other improvements.

"Even as we confront the immediate and unprecedented challenge of COVID-19, we remain laser-focused on making smart investments in our infrastructure, our workforce and our lasting prosperity," Los Angeles Mayor and Metro Board Chair Eric Garcetti said. "The Foothill Extension project is a down payment on a more connected, dynamic and equitable future for Angelenos, and it will pave the way to good-paying jobs and a stronger transportation network across our region."

The first major construction activity begins with the rebuilding of the at-grade street crossing on Gladstone Street in the city of San Dimas and will require a three-month full closure of the street at the railroad crossing to vehicles and pedestrians.

When completed, the Foothill Gold Line will provide connections to regional destinations like the Los Angeles County Fairplex, more than two dozen more colleges and universities, historic downtowns, museums, regional parks, open space areas and more.

In addition, the extension will provide a direct link between the Metro and Metrolink systems, allowing riders from each system to easily transfer.

The construction authority, citing a study by Beacon Economics, stated it estimates that during construction alone, the Foothill Gold Line from Glendora to Montclair will create as many as 16,000 jobs and up to $2.6 billion in economic output for the region, as well as up to $1 billion in labor income and potentially $40 million in tax revenue.

Once completed to Montclair, the line is estimated to add more than 18,300 riders to the Metro system every day.
