Future Planning

As part of a long-range vision, SJCOG and member agencies are proactively addressing future needs and investing in projects to improve connectivity, reduce congestion, and improve air quality. Such projects with potential Measure K funding include:

I-205 Managed Lanes Project

Measure 205 manage lanes 1K is funding project design alternatives and an 
environmental analysis of a project on Interstate 205 west 
of Tracy that will ease 
congestion, enhance traffic safety, 
reduce  vehicle emissions, and improve air quality in the 
region. It will be more convenient for 
commuters and other 
motorists traveling to and from the San Francisco Bay area 
for jobs, entertainment and recreation. The analysis 
 for the 
I-205 Managed Lanes
 project will look at possibly including 
carpool lanes, bus and/or passenger rail service in the 
median, and toll lanes, the first in the region. And 
depending on the ultimate plan, overpasses, underpasses 
and interchanges will be altered as needed. Transit hubs could include park-and-ride lots, electric vehicle charging stations, and 
bus and train stops, making it easier for 
commuters and others to get around. The project approval and environmental document 
are scheduled to be completed in 2023.

Commuter Rail Expansion (Valley Rail)

Valley Rail expands the Altamont Corridor Express (ACE) service between Sacramento and Merced. Valley Rail will add three 
round trips between Merced andValley Rail (002) Natomas, which will connect to 
ACE trains traveling to and from San Jose at the North Lathrop 
Transfer Station. There will be an additional ACE round trip 
between Stockton and Natomas, which will connect to San Joaquins
trains at Stockton. Valley Rail will also add new daily roundtrips
for the Amtrak San Joaquins service to better connect San Joaquin
Valley travelers with the Sacramento Area and extend the existing 
passenger rail service by approximately 120 miles and includes 16
new stations. The final environmental impact report for the ACE 
Extension to Modesto/Ceres, including the North Lathrop Transfer 
Station and Lathrop Wye Project, was certified in August 2018. 
The final environmental impact report to extend ACE for the
Sacramento Extension was approved by the San Joaquin Regional
Rail Commission in October 2020. Construction of the North 
Lathrop Transfer Station and the Lathrop Wye is scheduled to 
begin in 2022 with service beginning in 2023.

The Altamont Corridor Vision

This long-term plan will establish a universal rail corridor connecting the San Joaquin Valley and the Tri-Valley to San Jose, 
Oakland, San Francisco and the Peninsula. This project will aid in reducing congestion, decreasing travel time, improving 
efficiency, and making overall improvements across Northern California. The project is currently unfunded, but ACE is 
seeking shorter-term improvements to the rail over the Altamont Pass.
