Yes this is a section of I-80 that has to respond to both Sacramento and Bay Area commuter traffic at the same time.
Here are some of the Original shots for now with the widening project as of October 2022.

Some of the new median barriers are being made to make the new express lanes from Fairfield to Vacaville.

Here is more details this project is estimated to be completed in 2025.
Nice! I'll be using these when I pass through it should make the experience much better. For some reason this stretch seems to take the longest in regards to perception of time when driving from Tahoe to the bay or vice versa. Hopefully this project will help with that.

I'd agree that this will be a nice improvement, although could you California folks please upgrade I-80 from the 1960s 6 lanes to 8 lanes from the Yolo Causeway to Vacaville as well. I would greatly appreciate that. Tolled express lanes would be fine.

I feel like the inordinate number of lane drops and additions between the causeway and I-505 is part of the reason for all of that congestion, especially in the area immediately around CA-113. A consistent profile, even with fewer lanes, would probably move smoother vs the constant merging and people dropping into the right lane to blast past stopped traffic.

I hope i-80 from Dixon, Davis all the way to West Sacramento can widen their lanes the same way. I-80 Solano County has to respond to both Sacramento and Bay area commuters at the same time. Sure there was a time when I-80 in Solano County was considered being in the Middle of Nowhere at one point but now housing expenses in San Francisco and Sacramento became an issue and we had to step up and provide housing in the region in the same way Tracy and Modesto provides housing for San Jose Commuters.

Some relief is on the way for I-80 upgrades in Yolo County!
I drove through the work zone on Friday the 11th. Talk about a mess. Both directions were backed up for several miles. If that's anything like what normal traffic is in that area, these upgrades can't come soon enough.

Here is the study showing how NorCal is becoming a Megaregion that's merging together such as North San Joaquin, Greater Sacramento and Bay Area are merging together. In this case Solano County is viewed as the outer suburbs of both Sacramento and Bay Area at the Same time.

I know recently they replaced shrubs on the median for Concrete Median Barriers on I-80 to make way for the express lanes between Fairfield and Vacaville. Yes this is the merging point between Sacramento area and Bay Area traffic coming together at this location.

Here is a Column on SF Gate explaining traffic jams on I-80 and how there are a factor on both Sacramento and Bay Area Commuters.QuoteWhat was once a traffic issue snarling peak commuting hours has become a customary inconvenience that's been further exacerbated by a population shakeup in recent years as more people moved eastward from San Francisco. As previously reported, the top in-state destination for people leaving the Bay Area was Sacramento.
"During regular M-F weekday commute hours, the morning and evening commutes along I-80 in Solano County seem to be increasing," Jacala said. "That's because more people seem to be buying more affordable homes in places like Vallejo, Fairfield, Vacaville and Dixon. Then commuting to either the Bay Area or Sacramento."
The trend is supported by available traffic data. Transportation analytics firm Inrix shared numbers with SFGATE focused on I-80 between I-680 and Interstate 505 for weekdays from 2019 to 2022. The firm found that eastbound evening traffic has worsened since 2019, adding a 5% increase in travel time.
Was up there recently and it's still kind of messy on weekdays, but the weekend was smooth sailing.
Here is the shot by Full Length Interstates. The Full Video is about I-505 but at the start it shows the construction on I-80 in Vacaville.

Here is a related topic but it involves the rumored "New City" in Solano County, CA whose investment group is identified as Flannery and Associates.
They're fooling themselves if they think with no infrastructure that they can make a "thing" out there.

Also a new city would have to go through multiple reviews like earthquake risks, wildfire risks, flood risk, how it affects the Sacramento Delta and Suisun Bay are all factors here along with risk to national security given this is what sparked the investigation. Note this new city would require CA-113, CA-84, CA-160 and CA-12 to meet freeway standards if this is really going to exist the way it's being hyped here.
This is all hype but it needs to be backed with a state and federal review.

Here is an update on the I-80 Project in Vacaville as of October 2023.

Here is the current status on the Toll lanes added on I-80 Solano County. The current estimated time to have them fully open is in late 2025.
https://511.org/express-lanes/I-80
Too bad it's only open on the WB side right now. When I'm in the area, I'm usually approaching this from the EB side and they still lose a lane past Air Base Pkwy.
Saw some testing activity on the new toll gantries when driving through recently. All the lanes are open, so I guess it's just a matter of the electronics now.
I see the signs for toll lanes on I-80 but the transponders have not been activated yet.
Will there eventually be toll lanes on Interstate 80 from Oakland all the way to Sacramento?
Quote from: The Ghostbuster on September 29, 2025, 12:09:27 PMWill there eventually be toll lanes on Interstate 80 from Oakland all the way to Sacramento?
Well, to do that, you would need HOV lanes all the way from Oakland to Sacramento. The current HOV map ( https://gisdata-caltrans.opendata.arcgis.com/datasets/aea15307150f4463909d5cc1b8da6232_0/explore?location=38.192092%2C-121.959403%2C10.74 ) shows that the lanes are currently incomplete.

I would relish the day that came to fruition, but I think getting that kind of expansion through Vallejo is going to be a pricey proposition. This is a very old stretch of highway, on a constrained right-of-way, traversed by several very old bridges. I'm not saying it won't happen, I'm just saying that there is a good reason why no appreciable expansion has happened in Vallejo in decades.
Honestly, I wish Caltrans would do more promoting 680-24 as an alternate when busy. I've used 680 to get around many jams, and if there ever is the political desire for a continuous HOT facility, that would be the easiest place to route it.

680 sure, but isn't it pretty difficult to make improvements or additions to 24 going over (and through!) the mountains?

I'd imagine Google Maps would route people that way now if I-80 was jammed.

Google Maps and Waze generally *do* make such adjustments. That said, during busy times CA-24 and I-680 are subject to their own areas of extreme congestion. Hopefully when the gap in HOT/HOV lane on 680 North between Livorna Rd. and CA-242 gets closed, some of that congestion will go away and this will become a more viable route. I predict that the bottleneck would then become the stretch of 680 between the Benicia Bridge and Cordelia, where it remains only 2 lanes in each direction.

Unless you included 780 in that then I wouldn't recommend that, the section between 780 and Cordelia is such a mess with only 2 lanes in each direction. Hopefully they widen it eventually when they connect the interchange to the 12 interchange.

THey are doing work at the Route 12, I-80, I-680 interchange near Cordelia. It has been going on for years. See my pages on any of the routes for details (e.g., https://www.cahighways.org/ROUTE680.html )

This project and the 680/CA-4 interchange rebuild are 2 projects that I have no expectation of seeing completed any time soon. Things have been so drawn-out and underfunded, both have involved the trickling-out of piecemeal phases over the past 2 decades. Both are real monuments to the inefficiency of construction and the funding formulas for these improvements.

No, I get that and I've seen that work. I don't understand where 780 comes in, though.

The section of 680 between 780 and 80 is incredibly overloaded and backs up regularly, but 780 is very underutilized.

680-780-80-12 seems like kind of a roundabout path though. If you were taking 780 maybe just cut up CA-29 at that point? Probably slower though due to the density of that area. Haven't really driven there much myself.

This section has been screaming for expansion for a couple of decades now. I'm sure that a HOT lane will eventually appear here, but I don't see it happening until more progress is made on the 680/80/12 interchange project. Perhaps my children will benefit from it one day if they still live in this area.
