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

Construction Activity: As part of the 9.1-mile Foothill Gold Line light rail project, on December 5, 2022, crews will permanently close Santa Fe St. and Magnolia St. (south of the railroad tracks) between Garey Ave. and Pine St. Both streets are being permanently closed to become part of the future parking facility for the Pomona Gold Line Station, now under construction. After the street closures, access to the Metrolink Station/parking will be maintained via Grevillia St., Pine St., Fulton Rd., & Arrow Hwy. For detour map please see this notice: English/Spanish

Metrolink’s Pomona North Station Parking lot: There will be occasional closures at the Fulton Rd. parking entrance and partial closures of the Santa Fe St. parking entrance. When the closures are in place, work crews will assist with traffic control in and out of the parking lot.  Crews will continue with the construction of the Pomona Gold Line Station and light rail track installation. Starting early 2022, crews closed specified parking areas/spaces to make room for the new construction. This phase of construction is still ongoing and will last thru the beginning of next year. A minimum of 100 parking spaces, closest to the train platform, are currently still 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.
