Transbay Joint Powers Authority (TJPA) has secured funding commitment of $3.4 billion with entry of The Portal, also known as the Downtown Rail Extension (DTX) Project, into the Engineering phase of the Federal Transit Administration’s (FTA’s) Capital Investment Grants (CIG) program.

The cost of DTX was estimated in 2023 at $8.26 billion. The federal funding commitment of $3.4 billion, together with existing local funds committed and budgeted for the project (including Regional Measure 3, sales tax measures Proposition K and L and tax increment funds) brings The Portal to over two-thirds funded. 

Delivery of The Portal will complete the Transbay Program by extending Caltrain’s system from its current terminus at Fourth and King Streets into the multimodal Transit Center in downtown San Francisco, fulfilling the voter mandate of Proposition H in 1999 and bringing the statewide California High-Speed Rail system into its northern terminus. The Portal also unlocks the potential for a conventional gauge Transbay rail connection through downtown San Francisco.

The Portal is one of 18 projects nationwide in the New Starts program that funds new projects or extensions to existing fixed guideway systems with a total capital cost of $300 million or more. Acceptance into the Engineering phase of the CIG program is the second step of the three-part process. The Portal was accepted into the Project Development phase of the CIG program in December 2021. 

The TJPA is working with partners from all levels of government to close the funding gap and is focused on obtaining funds through the Greenhouse Gas Reduction Fund.
