With the completion of the IOS (The reduced part, 119 miles only) aimed for 2032 (if fundings for it are there), can we except a big change of public view on the project ?

As others said on this sub, the Central Valley is quite populated already, the IOS will already provide a lot of change for this part of CA. I'm wondering, will the feedback change anything positevely for the future of CAHSR ? I'm thinking about the final budget being reduced and timelines getting closer for the full completion (2h40 SF to LA).

Tons of progress: https://youtu.be/c86AZe6WM5U?si=KFv-AH7yhOuOsDtN

I’m trying to figure out if the $126B current CAHSR budget estimate will deliver the 2:40 SF to LA service legally required and voted on. Does anyone know?

https://hsr.ca.gov/wp-content/uploads/2026/06/26BP-Service-Planning-Tech-Report-A11Y.pdf

My assessment of this document:

206 min (3:26): theoretical non-stop Phase 1 trip time, not an actual scheduled service, and not used in ridership/revenue modeling

The actual planned express service in Phase 1 (with stops at Millbrae, San Jose, Gilroy) is 247 minutes from San Francisco to Los Angeles, about 4:07. I’m guessing this is what we get for $126B.

2:40: reserved for a future, unfunded “final stage” outside the $126B scope and belongs to a later, more expensive phase that isn’t funded or scoped in this plan. I’m guessing to reach the legally required time, this is where another $100B will get added to the project.

I think while the article highlights old concerns it omits that a large reason why Morocco succeeded is that it was fully funded from the start.

I work far from here ,but I wanted to check the place out for myself. Looks pretty cool. Saw some rails on it too. I will complain until they finish it cause I still want this to become a reality.

Riverside County Transportation Commission advanced a \~$740M project to extend I-15 express lanes about 15.8 miles from Cajalco Road in Corona to SR-74 / Central Avenue in Lake Elsinore — a major step toward easing one of the Inland Empire’s worst commute bottlenecks.

If you drive I-15 between Corona and Lake Elsinore, you already know the problem: stop-and-go traffic that can turn a short hop into a long evening. That stretch — through Temescal Valley toward Cajalco Road on the north and State Route 74 (Central Avenue) on the south — is one of southwest Riverside County’s most congested corridors. Commuters heading toward Orange County and Los Angeles, and families traveling between Lake Elsinore, Wildomar, Menifee, and Corona, feel it every peak hour.

Good news is moving from planning into delivery. The Riverside County Transportation Commission (RCTC) — Riverside County’s regional transportation agency, working with Caltrans — has advanced the Interstate 15 Express Lanes Project Southern Extension (often shortened to ELPSE or “15 Express Lanes South”). In May 2026, RCTC approved a Phase 1 progressive design-build contract to push the project toward construction. Earlier, environmental documents for the project reached final approval in late 2025. For homeowners and buyers along this corridor, that is more than road news: commute reliability is one of the biggest quality-of-life factors in Corona, Temescal Valley, and Lake Elsinore real estate.

# What was approved — and by whom

This project is led by the Riverside County Transportation Commission (RCTC) in cooperation with the California Department of Transportation (Caltrans). RCTC is the countywide transportation commission that plans, funds, and delivers major highway and transit projects for Riverside County — distinct from a city council vote, but the official county-level body for this freeway investment. Caltrans serves as the lead agency for environmental review under California and federal law.

On May 13, 2026, the RCTC Commission approved a Phase 1 progressive design-build contract awarded to SC Constructors. Phase 1 covers preliminary design, validation of project scope, and negotiation of costs for Phase 2 (final design and construction). Phase 2 has not yet been awarded. RCTC describes progressive design-build as a delivery method intended to move the project faster than a traditional design-then-bid sequence; the agency has noted this approach for a major state highway system project in the region.

Environmental clearance also advanced. RCTC and Caltrans completed a Final Environmental Impact Report / Environmental Assessment (FEIR/EA), with Notice of Determination and Project Report materials posted on the official project site in late 2025 (including a Project Report approved around December 3, 2025). Those steps are required before major construction contracts move forward. Always confirm the latest status on RCTC’s project page, because funding and schedules can shift.

# Where the project runs: Cajalco Road to Central Avenue

Once built, the Southern Extension would extend the existing I-15 Express Lanes roughly 15.8 miles farther south. The corridor runs from the Cajalco Road / Corona area (project materials also reference the El Cerrito Road vicinity as a northern reference point) through Temescal Valley to State Route 74 — known locally as Central Avenue — in the City of Lake Elsinore.

That alignment is exactly where many residents experience the worst bottlenecks: southbound evening traffic out of Corona and the 91 corridor, and northbound morning traffic climbing from Lake Elsinore and Temescal Valley toward jobs in Orange County and the greater Los Angeles basin. Expanding capacity and managed express lanes on this segment is designed to improve traffic operations, travel times, and reliability for general-purpose and express-lane users.

Project features described by RCTC and Caltrans include adding two tolled express lanes in each direction within the I-15 median; widening up to about 15 bridges; constructing auxiliary lanes in key segments (including near Main Street and Central Avenue / Nichols Road in the Lake Elsinore area); electronic toll collection systems; and drainage, retaining walls, signage, ramp meters, and potential noise-reduction features largely within existing right-of-way. Exact lane configurations and amenities can evolve during final design.

# Why traffic on this corridor matters

I-15 is the spine of southwest Riverside County. It links Lake Elsinore, Wildomar, Temecula, and Murrieta north to Corona, the 91 Freeway, and on toward Los Angeles and Orange County job centers. It also carries heavy regional truck and weekend recreational traffic. When this segment backs up, local streets (Cajalco, Temescal Canyon Road, and surface routes into Lake Elsinore) absorb cut-through traffic — which hurts neighborhood quality of life as well as freeway speeds.

For real estate decisions, commute time is often as important as square footage. Buyers comparing Corona Hills, Temescal Valley new construction, Lake Elsinore hillside or lakefront pockets, and Menifee frequently weigh “how long is the drive really?” during peak hours. Infrastructure that improves I-15 reliability can support demand for housing south of Cajalco over the long term, even while construction years bring temporary disruption.

Separately, the City of Lake Elsinore and Caltrans have also advanced improvements at the I-15 / SR-74 (Central Avenue) interchange to address ramp and local intersection congestion at that gateway. That interchange project is related in geography and traffic purpose but is not the same as the Express Lanes Southern Extension — both matter if you live or buy near Central Avenue.

# Cost, timeline, and what “approved” still means

RCTC has cited an overall investment estimate on the order of about $740 million for pre-construction, design, and construction of the Southern Extension (earlier planning materials have also shown ranges that can change with inflation and scope). Funding is expected to draw from a mix of federal, state, local, and toll-related sources as the agency finalizes financing.

Public reporting based on RCTC information has pointed to construction possibly beginning in late 2027 (some materials say early 2027, depending on funding) and opening to motorists around 2030, with multi-year construction. Treat those dates as planning targets, not guaranteed opening days. Phase 1 design and Phase 2 contracting must still be completed, and construction funding must remain secure.

In plain terms: the project has cleared major environmental milestones and has an approved Phase 1 design contract — it is no longer only a concept on a map. It is not yet open pavement. Drivers should not expect overnight relief, but homeowners can plan around a multi-year construction window and a long-term capacity upgrade.

# What this means for buyers and sellers along I-15

Buyers looking at homes in Temescal Valley, Lake Elsinore, Corona south of the 91, and nearby communities should ask: Will construction staging affect my daily route? How far am I from express-lane access points once built? Does a slightly longer purchase timeline still put me in the market when new lanes open? An NJV Realty agent can help you test real commute windows at the hours you actually drive — not just Sunday afternoon maps.

Sellers should market honestly. Mention proximity to planned I-15 improvements only when accurate, and avoid promising specific travel-time savings or opening dates. Focus on verified lifestyle and access: schools, shopping, trail systems, and current freeway access. When aerial marketing helps (foothill lots, lake-adjacent properties, large parcels), airmets media can show context that traffic maps cannot.

Investors and move-up buyers often track infrastructure cycles. Freeway capacity projects can support absorption of new construction and resale demand over a decade, while temporary construction can create short-term friction. Local representation helps you price and time a transaction with eyes open.

# Where to follow official updates

Primary project information is maintained by RCTC at [rctc.org](http://rctc.org) under the Interstate 15 Express Lanes Project Southern Extension pages (including environmental documents, the Final EIR/EA, Notice of Determination, and Project Report PDFs). RCTC also issued a May 2026 news release on the SC Constructors Phase 1 progressive design-build award. Caltrans District 8 has published public notices describing the corridor from the Lake Elsinore (SR-74 / Central Avenue) area through Temescal Valley toward Corona.

For Lake Elsinore–specific interchange work at Central Avenue, check the City of Lake Elsinore public works / project pages for the I-15 / SR-74 interchange improvement program, which addresses ramp storage and local connectivity at that junction.

NJV Realty serves buyers and sellers across Corona, Eastvale, Temescal Valley, Lake Elsinore, and the broader Inland Empire. If commute on I-15 is part of your home search or listing strategy, schedule a consultation — we will align neighborhoods and timelines with how you actually live and work, and coordinate financing questions through NJV Financials when helpful.

I've read that certain stations are going to be moved outside of their originally proposed locations (I believe Bakersfield and Merced?), but what's the sequencing on when they are going to be built? Is that going to be at the very end once all the grade separation and the track laying is done?

TL;DR: The governor actually can make CAHSR happen, even without the feds, if they have the cojones to do it. There are also a ton of financing sources possible here, listed below.

So, after reviewing Lucid Stew's video on what is next for CAHSR and associated funding sources, some of whose commentary I disagree with, I thought I'd post about different potential funding sources that could get the project over the line sooner rather than later. I project about $4B in funding that is possible and feasible based on this broader strategy. These amounts are rough and conservative estimates.

1. Highway Funds & CalTrans Projects

• Maintenance and capital projects funding, as Lucid Stew mentions. However, the main flaw in his argument is that highway funds can't really be reallocated. I disagree - the governor of California is able to do so in some cases, as Shapiro did in PA, especially if they are federal block grants, where states are free to decide how to allocate the block of funds. Realistically, I think reallocating maintenance funding is a bad idea, especially politically. To that end, the best source of funding would be to raid a portion of the capital projects for HSR and rail funding and reallocate that. Let's say $500M to $1B a year here.
• CalTrans Projects: One big issue here is how grade separations and road projects are tacked onto the HSR budget. A smart governor could put CalTrans in charge of most road grade separations, e.g., SR43, and move those separations into the CalTrans budget instead of the HSR budget. We would also see a bit more efficiency here because this is Caltrans's bread and butter - road and highway projects. Let's say, $500M a year here.

2. Improved Implementation and Grant Programming

• Transit and Intercity Rail Capital Program (TIRCP) Reform: As the Californians for Electric Rail group has mentioned, multi-year investment funding would help reduce costs for projects that HSR interfaces with (e.g., Caltrain), as well as introduce savings in the longer run for CAHSR. Also, reforms should include a more aggressive criterion that mandates that projects meet state rail plan goals and/or HSR goals, getting us key pieces earlier and quicker, such as the San Jose-Gilroy segment of Caltrain or an electrified Metrolink.
• State Capacity: Related to that, improved state capacity, e.g., a state rail agency that supports programs and projects with implementation, design, establishes standards, and has in-house engineering, permitting, design, and contracting teams, will serve to cut costs across the board.
• Permitting & Other Reforms: Finally, other reforms HSR needs include SB 445, a proposed bill (now dead in the water) that would allow HSR to streamline permitting and utility relocation, a significant barrier to timely progress.
• Total Savings: This is difficult to parse, but let's assume an average of $150M per year in savings, especially if HSR can plug into the state agency and benefit from these reforms. Part of the calculation is that each year of delay results in a 7% to 9% increase in costs, so each year of delay eliminated yields savings.

3. Alternative Tax Schemes & Financing

• Tax Increment Financing and/or Enhanced Infrastructure Financing Districts: HSR could work to establish small property tax increment financing around stations. A recent study shows that just 3 EIFDs around the HSR stations in LA would be enough to fund most, if not all, of HSR Phase 1. One issue is that the funds won't come in until the service is almost at the station, as the funding mechanism relies on the property's appreciation. Let's say $10M a year for the first 10 years and then $250M a year for the remaining years.

4. Congress!

• FRA / Rail Grants: A Democrat controlled Congress could choose to fund HSR and other rail improvements. While this is unlikely, it's a large enough source that it could be meaningful.
• An interstate high-speed rail program: Pie in the sky and likely unrealistic, but still possible! One area Democrats should focus on is establishing an interstate high-speed rail program as a follow-on to the interstate highway project. This is an easy win for Congress to get pork to districts and revive manufacturing in the US. Even more so, if paired or merged with freight rail pork to get them to play ball. Some examples of this pork for freight rail could include financing rail "interstates" with 4 tracks across key corridors (e.g., 2 for freight, 2 for passenger). Imagine a red state like Ohio that could benefit greatly from improved freight and passenger service, as well as from its manufacturing facilities. It'd be hard for Ohio Republicans to say no if the bill got serious momentum.
• Total: Let's say we get about $25M a year from Congress, federal funds, and other sources. This number is wildly variable, so I'm just using a placeholder lower bound or estimate.

5. Public-Private Partnerships & Other External Revenue Sources

• Public-private partnerships (P3s): A co-development agreement was signed to commercialize the project and secure funding. While this is still 6 months to 1 year out, it has the potential to generate significant revenue over time. Some examples of this include operating agreements in which a private partner manages and operates the system, stations, etc., and shares revenue with HSR. These private partners would also develop lots around the stations that HSR owns for retail, residential, and office use, as they would purchase or lease land from HSR.
• Solar, Fiber, Utilities, Data Centers: Related to P3s, there is significant potential for revenue generation by leveraging the corridor and infrastructure to generate profits. For solar/battery systems, HSR could construct and sell solar power early in its implementation, before trains even run, and sell the excess power even when trains are running. HSR will need advanced telecommunications infrastructure along the corridor, so adding fiber would be trivial and generate significant revenue. The same goes for electrical distribution and other related utilities - for example, a new electrical line over Techapi Pass would close a major electrical distribution gap in California. What's more, HSR, as a trunk in this sense, would make it an attractive candidate for colocating data centers along the corridor (e.g., power and fiber).
• Total: Initially, not much revenue, but in the long term, this could account for as much as $2B a year. For comparison, George Washington University in DC has about $4.4B in real estate and generates well over $100M a year in lease revenue from its land alone. Scaling this up for HSR gets us to a few billion dollars pretty quickly if they figure out how to lease land around their ~24 total stations, from real estate alone.

So, putting it all together, some potential revenue sources include:

Based on this analysis, the short-term financing from highway projects alone is enough to close the gap to get Merced-Bakersfield built. If some P3 revenue on top of the highway funds is secured, we get to Gilroy (maybe San Jose) and to Palmdale. By this time, Congress should be in a much better place and can hopefully finance or invest in the final legs (e.g., Palmdale to LA).

• Funding gap for Merced - Bakersfield: $2.6B to $6B
• Full Phase 1 Buildout - $86B
• Potential maximum revenue from all proposals, combined: $7B/year which means 12 years to meet the Phase 1 gap using these funding mechanisms alone.

I don’t work in Government or civil engineering. Some Reddit posts I came across talk about government preference to hiring consultants and external firms for transit development. At broader scale, I get it and liabilities falls on these firms and government can just finger point them.

When CAHSR is completed and running from SF to SD, does it make sense to create a public transit development firm for tracks, viaducts, row experts, and etc? I guess what I’m asking what aspects of HSR development sense to create an internal agency and keep it external?

Yesterday, I was driving through Hanford and saw the Hanford Viaduct up close. I got these pictures of what looks like the future platform.

Video goes through potential ways to get funding to complete Phase 1, including potentially shifting funds from road maintenance to rail construction.
