Gold Line Construction Update

This month marks two years since the Construction Authority executed the design-build contract with KPJV. Over that period, the design for the project went through multiple rounds of increasingly detailed engineering – reaching substantial completion this past August. Work on the first major milestone task of construction – relocating nine-plus miles of freight track that initially sat in the middle of the rail corridor – is now nearly complete. Reconstruction of the 21 at-grade crossings is already more than half complete, and many of the smaller bridges are nearing completion as well. The four light rail bridges being built over major streets are all underway, and the community will soon start to see those bridges taking shape.

As you know, much of this progress occurred during Covid-19, and required unprecedented cooperation by the project partners: KPJV, the corridor cities, Metro and other project third parties. It has also taken the support and patience of the community at large. We want to take this moment to thank those that have supported the project’s progress these past two years. The coming months will continue to be very significant for construction. The team will do our best to minimize impacts while working to get this important project built as quickly as possible. Thank you for your ongoing interest and support.
Now to the latest updates…


Grade Crossing Reconstruction in Glendora, San Dimas and La Verne

Crews are currently underway with the reconstruction of three grade crossings: Pasadena Ave. in Glendora, Walnut Ave. in San Dimas and D St. in La Verne.

A month ago, crews completed the reconstruction of the Vermont Ave. grade crossing, allowing it to reopen to motorists and pedestrians on September 24. However, West Ada Ave. north of the crossing still remains closed to allow crews to complete utility and street work. As a reminder, West Ada Ave. south of the crossing is permanently closed.

Most recently, at Elwood Ave., crews returned for a second, short closure of the crossing to complete underground utility and street work. Over the past few weeks, crews built new storm drains, installed underground conduit for new streetlights and completed a host of other improvements and activities - which allowed the street to reopen to motorists and pedestrians on October 22.

At the Pasadena Ave. crossing, crews are nearing completion on the installation of a new underground water line (that previously did not exist) across the tracks, one of the many betterments as a result of the project.
Finally, over the next few weeks, it is also anticipated that the Walnut Ave. (San Dimas) and D St. (La Verne) crossings will be completed and reopened to motorists and pedestrians. At both crossings, crews have installed the relocated freight track and continue to make progress relocating and protecting underground water, sewer, gas, communications and power lines. Crews will then move on to installing two new light rail tracks and safety equipment, and rebuilding the roadway, curbs, gutters, sidewalks and medians.


Upcoming Street Closures for Grade Crossings and Bridge Work in Glendora, San Dimas and La Verne

In November, the following streets will be fully closed at the railroad corridor for grade crossing reconstruction and/or bridge work:
  • Route 66 (Glendora) - Ten-day full street closure
  • Lone Hill Ave. (Glendora) - Two-day full street closure with additional lane and periodic full directional closures
  • San Dimas Canyon Rd. (San Dimas/La Verne) - Eight-month full street closure (following Walnut Ave. reopening)
  • A St. (La Verne) - Four-month full street closure (following D St. reopening)
More information on these closures will be made available in the coming weeks. If you know anyone who may be impacted by these upcoming closures, they are encouraged to sign up for Construction Alerts at

Phase 3 of Bonita Ave./Cataract Ave. Intersection Reconstruction - Construction of New Light Rail Bridge Continues (San Dimas)

Crews are currently in Phase 3 of a four-phased construction plan to reconfigure the Bonita Ave./Cataract Ave. intersection in San Dimas. This phase requires a full closure of Cataract Ave. north and south of Bonita Ave. through June 2022. Bonita Ave. traffic will remain open in both directions, and the eastbound Bonita Ave. to southbound Cataract Avenue movement will also remain open. For more information on the closure, click here.

Meanwhile, crews continue to make progress on the construction of the new light rail bridge. Over the past few weeks, crews began construction on the light rail bridge’s west and east abutments (the supports at both ends of the bridge), as seen in the photos above.

Both the intersection reconfiguration and the new light rail bridge are required by the California Public Utilities Commission (CPUC) for safety. You can also read a fact sheet that provides an overview of the intersection improvements and future light rail bridge (click here).


Other Bridge Work in Glendora, La Verne and Pomona

Elsewhere throughout the corridor, crews have also made progress on the construction of new light rail and freight bridges in Glendora, La Verne and Pomona. Overall, crews have now begun or completed construction on nearly all of the 19 light rail and freight bridges to be built from Glendora to Pomona.
At the intersection of Foothill Blvd./Grand Ave. in Glendora, the west approach for the future light rail bridge has been noticeably taking shape. As seen in the aerial photo above, crews continue to make progress building the retaining walls for the approach, which consists of custom form panels that feature the project’s citrus design and will measure nearly 1,250 feet in length.

To understand what the future light rail bridge over Foothill Blvd./Grand Ave. will look like, click here to see 3D simulations.

On the southeast corner of the Foothill Blvd./Grand Ave. intersection, crews recently completed the foundation work for a freight-only bridge over Little Dalton Wash (shown above) and will soon install the bridge girder. The freight bridge will cross the wash and exist alongside the future Foothill Blvd./Grand Ave. light rail bridge that will cross the intersection. While light rail trains will travel over the intersection in the future on the light rail bridge, freight trains will continue to travel at street level.

Alongside the existing freight bridge over Route 66 in Glendora (which will remain intact), crews have begun constructing the west and east abutments for the new light rail bridge. As noted above, in late November, a ten-day full closure of Route 66 at the bridge will take place to allow crews to complete work on the bridge foundations. More information will be available for that closure soon.

Following the recent, successful installation of the concrete girders for the new light rail bridge over San Dimas Wash in Glendora, crews have moved on to completing the rest of the bridge. Last week, crews poured concrete for the bridge deck that will carry two new light rail tracks in the future. The adjacent relocated freight bridge was already completed and is ready for use by freight trains (and, it seems, for crews wanting a front row seat to watch the deck concrete placement).

At Live Oak Wash in La Verne, crews recently completed the construction of the west and east approaches, as well as the installation of five concrete girders, for the new light rail bridge. This new bridge will carry eastbound and westbound trains over the channel in the future. The adjacent relocated freight bridge was already completed and is ready for use by freight trains.

Finally, in Pomona, crews continue to make significant progress on the deck for the new light rail bridge that will carry eastbound trains over the Thompson Creek channel. As seen in the photo above, the walls for the bridge deck will feature the project’s citrus slice design pattern.

This bridge will be an extension of the existing channel structure that currently carries a temporary freight track. In the future, crews will remove the temporary freight track and install the westbound light rail track in its place. At that time, the freight track will be relocated onto a separate structure to the north that was recently completed.


Glendora Station Update

Below the future Glendora station platform, crews are installing underground conduit that will house the communications and power lines for the station. The station, which is located between Vermont Ave. and Glendora Ave., will be a center platform station, with light rail tracks on either side (one for westbound and one for eastbound trains).

Freight Track Relocation Continues

Crews are actively working in San Dimas to remove the existing freight track and install the new track in its relocated position. Where possible, the relocated freight track will be comprised of recycled rail pieces that were removed earlier in the project. To accomplish that, crews work at a yard in La Verne, welding the rail sticks into 960-foot-long pieces. Overall, the freight track relocation work is more than halfway complete and is anticipated to be ongoing through the end of the year. Light rail construction is anticipated to start soon in Glendora.
