405 Sepulveda Pass HO/T Lanes

[Plutonic Panda]

Just to carry on a conversation from another thread I had with cahwyguy one of the alternatives does in fact add an additional travel lane each way:

https://storymaps.arcgis.com/stories/88d93c10a2164de89349bbcd30bcf6b2

That would alternative 3. I'm not sure which way they're gonna go. But my guess would be number three since they did the same thing with the 105. So I'm not sure why they wouldn't plan that for this corridor, which would allow more cars to use it and generate more revenue.

As I noted in the other thread: They are way overdue on the Draft EIR (like by over a year), so it is still unclear what alternative will be chosen -- and I have a feeling things might change given the rail corridor selection recently made.

Change in what way? This seems to me, they will be given more space to work with without having to actually expand the width of the freeway itself. Frankly, I think in this area a project like this would be more supported by those who live nearby to add more toll lanes because they could probably afford it. I'm surprised the HOV to toll lane project on the 105 didn't get more pushback.

Metro is also poised to release their EIS for the I-10 express lanes which has almost identical proposals as the 405 Sepulveda HOT lanes do. My guess is they will go with two total lanes each way since that's what they already have on their current I-10 HOT lanes system and the 110 HOT lanes. I'm not aware of anywhere in LA that has a single hot lane each way except the south 110 HOT lane. I'm also unaware if the Bay Area has any freeways that have two toll lanes each way. They seem to enjoy just simply converting an HOV lane to a toll lane and nothing more.

First: 405 lanes. Change in that I think they will anticipate less of a need for an additional lane in pass. The new Metro line will move a lot of student traffic off of the freeway, and the simpler HOT conversion will be less expensive and support VMT goals (which I know you disagree with).

Second: I-10 Express Lanes. I've seen nothing in the CTC minutes or discussions about engineering or planning for HOV lanes, let along Express Lanes, in the Santa Monica Segment. They would need Caltrans funding for a draft EIR, so that's unlikely (and there is no room).

There is an ongoing project to add Express Lanes to the San Bernardino Freeway, I think as far as SBD itself. The later phases of that are still in the engineering phases, so that's likely the EIR in process.

I could see your first argument, being the case, if the subway even gets built given the astronomical cost, and when it reaches the LAX airport station. But I think Metro knows the subway is not gonna be built anytime soon. I have no proof to back that up. I'm just talking out of my ass, so we'll see but this is gonna be a pretty remarkable new project for them, especially given the fact it's gonna be completely automated.

My opinion is they're still gonna need to be an additional lane for capacity improvements on the short term.

As I said: the San Bernardino Freeway segment, not the Santa MOnica segment. From what you posted:

Metro and Caltrans are planning improvements along the I-10 corridor between I-605 and the Los Angeles/San Bernardino County line—a heavily traveled route for drivers, carpools, and buses. Proposed options include converting existing carpool (HOV) lanes to High-Occupancy Toll (HOT) ExpressLanes, adding a second ExpressLane in each direction, or expanding HOV capacity. These upgrades aim to ease congestion, improve travel time reliability, and create a continuous ExpressLanes network into San Bernardino County.

Oh yeah, I don't see what they can do with the Santa Monica Freeway other than just do what they did with the 635 in Dallas and I don't see that happening in a million years so I think that freeway is gonna stay as it is for a while.

I'm also unaware if the Bay Area has any freeways that have two toll lanes each way.

Eastbound I-580 in Dublin/Livermore between El Charro Rd and just before Vasco Rd. TIL you can actually see the express lanes (one versus two) marked on Google Maps.

US 101 from CA 85 in Mountain View to Embarcadero Road in Palo Alto has had two HOV lanes in each direction since 2013-14, which have since been converted to HOT lanes as part of numerous Express Lane projects in San Mateo and Santa Clara (Phase 3, Phase 4, Phase 5) counties as of 2022.
