$49-million I-580 eastbound carpool lane opened to traffic

Original post made on Nov 11, 2010

The completion of the second phase of a new, 11-mile carpool lane on eastbound Interstate Highway 580 between Pleasanton and Livermore was celebrated at a ribbon-cutting ceremony near the highway yesterday.

Although this wasn't a Federal Stimulus project, it is a great example of why stimulus spending on infrastructure works. If the project was going to be done at some point anyways, the government is able to complete the project at far lower cost than if it had been done during boom times, while it keeps construction companies afloat and costruction workers employed.

In my mind, the thing that really helps is the very long weave lane added on the right between El Charro and Airway Blvd. This article doesn't make mention of it. So it isn't a four lane + one HOV lane highway anymore but a five lane + one HOV lane highway. That is allowing better traffic flow for cars getting on and off the freeway, giving plenty of room to merge. Cars already on the freeway don't have to slow up to allow short-distance merging and cars getting off don't have to slow up in a through-lane, slowing down traffic for everyone. They're also working on completing the fifth lane between Airway and the new Isabel interchange and that can only be good news.

Unfortunately, the article makes no mention that Ghilotti Construction also worked very hard on this project.

I agree with the earlier poster, the additional exit-only lane to Airway Blvd. makes a HUGE difference. If they turn the HOV lane into a toll lane, you can expect traffic to worsen again as drivers use the exit-only lane not to exit at Airway but to leapfrog ahead of slower traffic, as they do at Tassajara.

I took the drive today during afternoon commute hours. There was hardly any delay. The traffic speeds seemed about the same between the carpool lane and the two open left lanes. There didn't seem to be any advantage to taking the carpool lane. That reinforces my belief that it is the fifth lane that is helping improve traffic flow more than the carpool lane.

This has been needed for a very long time. Merging onto Airway to get to Las Positas after about 8:30am or so is NEVER fun... of course, the crazy drivers won't change, but maybe this will make conditions a little less dangerous; I've seen way too many fender benders on that little stretch of road.

Why do they want to tax drivers yet again?
They already tax gasolene, and car registration, supposedly to pay for the roads- then steal the money for other uses, and now they managed to install a Lexus Lane that mostly benefits the very well to do, to whom $5 is not a half hour's work, or the cost of a Pizza at Ceasar Ceasars.
A car pool lane to encourage less cars makes sense- allowing the rich to buy their way out of traffic jams, while leaving the poor stuck does not.

I'm a little confused, it doesn't say anywhere in that article that there is a plan to make it a toll this really in the works?

Too bad the 680 Carpool/Toll lane didn't make traffic better like this lane has. I think whomever designed the 680 Toll/Carpool lane should have taken a lesson from the 580 designer. The same designer could not have done both 580 and 680.

680 was a bust.

Westbound is in later stages of design and is scheduled to begin construction in Summer 2011 according to Caltrans.

Imagine if most of the commuters would be part of a carpool…it would be so much easier to get into the city. I tried the carbon dioxide and driving cost calculator of the carpooling network ( ) and they suggest huge savings: up to 2000$ and 1,5 tons of GHG per year.
