The Altamont Corridor Vision from Stockton to San Jose is estimated to need $9.7 billion in funding. The segment from Newark to North Lathrop is estimated at needing about $6.6 billion in funding. Improvements in the Altamont Corridor can be phased based upon the funding that is available. Incremental improvements can bring near-term benefits and help lead to the development of the ultimate Altamont Corridor Vision. In the short-term, the goal is to add two additional ACE round-trips between the San Joaquin Valley and San Jose and have full weekend service, and to initiate Valley Link service between Dublin/Pleasanton BART and North Lathrop (with 25 daily round trips). Another key short-term goal is the transformational implementation of a new 3.5 mile tunnel in the Altamont Pass and to straighten the alignment throughout the pass to enable speeds up to 125 mph that would be used by both ACE and Valley Link services (decreasing travel times by 11 – 15 minutes). Implementing these short-term goals is the first phase/highest priority for Altamont Corridor Vision implementation. In the mid-term, the goal is to add 4 additional ACE round trips to San Jose (bringing to total to 10 daily round trips) which will require improvements through the wetlands between Newark and Alviso to add capacity and raise the profile of the alignment to address sea level rise, and to extend the Valley Link service to Stockton (with a total of 30 round trips). The completed Altamont Corridor Vision is the long-term goal.
