Huh. Interesting posts. I've been commuting from Livermore to Brentwood for almost 11 years now. Many years ago, before all the road modifications, there were the occasional hairy moments... but in eleven years of commuting out there, I've had people end up in my lane twice. Once last year, near Camino Diablo, once about 8 years ago.
With the road reconstruction/relocation, and the rumble strips, and the plastic "posts" they put up, it's been a long time since we had a head-on. There's still the occasional accident- like any other heavily traveled road is going to have- but it's not the "Blood Alley" it was years ago.
I'm on Vasco from about 6:30am to just before 7am. Traffic heading into Livermore will stack up in the morning from the downhill descent (with the k-rails) just past the reservoir turnoff to the freeway (which is a parking lot heading west). Before the reservoir, it's easily doing 60mph. In the afternoon, though, it's a little worse. It seems to be averaging around 40mph, with occasional areas where it picks up, from Camino Diablo all the way back to Livermore.
It
does get windy, but the only spot where it's really an issue (and it
will move your ass across the lane!) is south of Camino Diablo, where 3 hills close right in on the road... there's two hills, a gap, and then another hill. That gap plays hell with the winds.
Since you'll be moving fairly slow due to traffic through there, though, it probably won't be an issue.
I was doing about 75 when I got the gust that blew me across the lane.
Personally, I actually enjoy the drive. It's stunningly beautiful in the Spring:
And the drive in is nice, too:
There are three roads I've experienced around here that totally creeped me out, made the Spidey sense tingle like crazy. Just feel....wrong.
Vasco is one, that road didn't make me happy at all. Brentwood had 6,000 people 20 years ago. Now it has over 50,000 people, and so many use Vasco at rush hour.
Other two are Hwy 12 through Rio Vista, and I-580 thru the Hwy 238 connector to 880.
There's been a couple of motorcycle fatalities on Vasco in the last 11 years, towards the Livermore end... and more than that on that connector between 580/880.
