Foothill Gold Line Light Rail construction project near Metrolink’s Pomona North Station - Ongoing

Construction activities near the Fulton Rd. crossing continue on the Thompson Creek Bridge. Crews have begun the Thompson Creek Channel modifications for the new light rail track and will start work on the new retaining wall for the Pomona Metrolink Station.

Metrolink’s Pomona North Station Parking lot: There will be occasional closures at the Fulton Rd. parking entrance. When the closure is in place, work crews will assist with traffic control in and out of the parking lot. Crews will begin the construction of  the Pomona Gold Line Station and light rail track installation. Starting on January 31, 2022 crews will be closing additional parking areas/spaces currently available to Metrolink riders to make room for the new construction. This phase of construction will last roughly one year. A minimum of 100 parking spaces, closest to the train platform, will remain available, including all of the existing 14 accessible parking spaces. Please be aware of construction signage and barricades throughout the parking lot separating the available parking spaces from the on-going construction activities.

White Avenue at the railroad crossing north of Arrow Highway: Rail construction at the White Avenue railroad crossing north of Arrow Highway is scheduled to begin on Friday, December 3rd and will be ongoing until April 30, 2022.
