Construction throughout 11.5-mile alignment of Gold Line Foothill Extension; here are some pics and details

The following is the latest e-news from the Gold Line Foothill Extension Construction Authority, the agency building the 11.5-mile project that will extend the Gold Line from eastern Pasadena to the Azusa/Glendora border. The project also includes a new rail maintenance facility in Monrovia. 

The design-build team, Foothill Transit Constructors (FTC), is on schedule to have the project’s design work substantially complete next month. The majority of the nearly 100 design packages have been “Approved for Construction,” and the remaining packages are nearing 100% design.

Significant construction is now well underway throughout the corridor. Bridge construction, utility relocation, grade crossing work, and even station construction can be seen at different points along the 11.5-miles.

Some of these activities require street closures and other impactful activities. Stay updated and don’t get surprised by construction!

A bridge begins taking shape in Azusa.

Below is a highlight of some of the construction activities now underway:


Utility relocation and mass grading is happening along the entire city of Azusa corridor, and the FTC team broke ground on the first major at-grade crossing in the city yesterday. Dalton Avenue will be closed for approximately six weeks to complete the crossing improvements. Click here to view the construction notice.

Additionally, to accommodate one freight track and two light rail tracks in the future, nine bridges at three crossings are also under construction in Azusa. Palm Drive is closed to thru-traffic for bridge work until May, and Foothill Boulevard has been reduced to one lane in each direction at the bridge crossing until September. Above is a photo of work on the bridge abutments at Citrus Ave.

The Duarte station is the first of six new stations to break ground, and work continues on the nearby Highland Avenue crossing until early March. (Duarte station-work is shown below).


Demolition of the old bridge abutments at Colorado Blvd is now complete, and work is underway on construction of the new dual-track bridge over this heavily-used street in the city. Colorado Blvd remains closed to thru-traffic until mid-April.

Gold Line Operations Campus Update

Mass grading is now complete for the 24-acre, $160 million Gold Line Operations Campus in Monrovia. FTC crews are now focused on utility relocation and foundation work on the main building. Utility relocation on streets surrounding the campus is also on-going.

  1. What will happen to the bridge over Huntington and Second? Visually, I can’t picture two tracks fitting on that portion of the right of way through Arcadia — the portion that is ‘elevated’ running from Huntington/2nd east to about Fifth Ave.

    • Hi there;

      The right of way will have two tracks – one in each direction. There’s enough room there.
