The entire 12.3-mile, six-station project from Glendora to Montclair is not yet fully funded. The westernmost 9.1-mile, four-station project segment from Glendora to Pomona is fully funded by LA County’s Measure M and State of California greenhouse gas reduction grant funding. That segment began major construction in July 2020 and is on budget and on schedule to be completed in early January 2025. The remaining 3.1-mile, two-station segment from Pomona to Montclair (including the Claremont and Montclair stations) is not yet funded. The Construction Authority continues to seek the funding needed to complete this final project segment, which as of late 2022 is estimated to cost $798 million.
Current project funding for the segment from Glendora to Pomona is coming from Los Angeles County, with support by the State of California. The majority of Los Angeles County funding is from the Measure M half-cent sales tax (approved by LA County voters in November 2016), along with nearly $100 million of residual funds from the Measure R half-cent sales tax not used to complete the Pasadena to Azusa segment. The project was awarded a nearly $300 million grant from SB1, through the State of California’s Transit and Intercity Rail Capital Program in 2018; the majority of those funds will be used in to complete the Glendora to Pomona segment, with approximately $80 million set aside for the project once it reaches San Bernardino County. San Bernardino County will be responsible for funding the remaining portion of the project cost in their county.
