SR-71 Expressway to Freeway Conversion Project
Location and Limits
In Pomona, between SR-71/I-10 interchange and the Los Angeles /San Bernardino County Line
SR-71 is a major regional highway transportation facility traversing parts of Los Angles, San Bernardino, and Riverside County. It is a connecting link for major east-west corridors passing through the area and serves as an inland passageway for interregional travel between San Diego and the easter portion of the Los Angeles area. The addition of the HOV lane will ensure that people are moving in a multi-modal way and reduce emissions to tackle climate change. With $43 million in SB-1 funding, this addresses a backlog of repairs and upgrades, while ensuring a cleaner and more sustainable travel network for the future. More importantly, this project commits to the direction of equity and comes with improving and expanding community partnerships, especially in underserved communities.
Phase 1 - 2.7 miles
These improvements will restore the facility and improve ride quality by rehabilitating the existing pavement with a pavement structure that will provide a service of 40 years for lane replacement and five to 10 years for slab replacement.
Phase 1 – South Segment (Mission Boulevard to LA/SB County line): Spring 2021 through Spring 2024
Phase 2 – North Segment (I-10/SR-71 interchange to Mission Boulevard): Spring 2024 through Spring 2027
Total Programmed Project Costs
Phase 1 - $174.544 Million
Q: What is SB 1?
A: Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017, invests approximately $5 billion per year to fix roads, freeways and bridges in communities across California, as well as strategically investing in transit. To date, Caltrans has completed more than 100 SB 1 highway projects with nearly another 500 projects currently in the works statewide and many more to come after that. This includes repairing or replacing 115 bridges and paving nearly 1,500 lane miles of the state highway system. In the coming years, SB 1 improvements will be even more visible to the public, with many big projects soon to go out to bid. For example, in our current fiscal year 2019-20, $5.5 billion of new work from multiple funding sources including SB 1 — or $2.5 billion more than last year — will go out for bid. Caltrans is committed to conducting its business in a fully transparent manner and detailing its progress to the public. For complete SB1 Details.
Q: Will this project close the freeway at any time?
A: Some lanes may be closed in either direction or both directions simultaneously to facilitate a safe work zone for workers and motorists. At least one or two lanes in each direction will remain open for traffic while work is underway. For the latest road conditions, go to Caltrans Quickmap. All work is weather dependent and subject to change.
Q: What are the current closures for this project?
A: Permanent Closures:
- Rio Rancho Road
- Old Pomona Road
- N Ranch Road
Q: Will this project be noisy at night?
A: Residents and businesses near project areas will experience noise from construction related activities. Loud noise may be experienced during the project's demolition phase.
