Isabel Avenue interchange now open

Original post made on Nov 10, 2011

Caltrans opened all ramps of the Isabel Avenue interchange at I-580 early this morning, completing construction work ahead of schedule and ending months of detours and traffic snarls as the work continued.

Okay - WHY is it a major artery to Vineyard? Why wouldn't you say to STANLEY ? It goes past Stanley first and is the quicker way to downtown Pleasanton.

This is a LONG awaited opening. Hopefully the travelers will be a happier crowd rather than the cranky, cut you off in a heartbeat, Flip you off attitude - with the FINGER sticking out the windows.
Smooth driving - watch out for Police calming traffic for the next 2 months!

for ???

With Stanley being only 45mph now and most the time one lane duringthe week in both directions-Vineyard is much faster. I take vineyard everyday to and from Livermore. Stanley is just to damn borning, too many gravel trucks NOT to mention the Wheels buses that think they have the right away and can run you off the road going 65 in a 45 mph zone. Then there are the bikes that love to ride in a traffic lane-
So guess what Vineyard is faster in the long run.

Right, like we're going to stop and wait at a light to make a left turn on to Stanley to get back to Ptown.

Vineyard is our drag strip, the throttle opens up on Wed!

What I want to know is who were the bureaucratic meatloaf-for-brains that approved Isabel as a two-lane road when it was redone a few years ago. It could have been a 4-lane road at a modest increase in cost. When this interchange opens, Isabel is going to be a clogged mess - make that a big, big, big clogged mess. I guessing the environmental wackos were somehow involved.

Livermore PD please be there to keep drivers from going too fast-this is not a highway and I hope folks remember to be courteous as they drive through a very beautiful area of Live More! We have waited so long . Next is BART and then many of us will us public transportation can't wait.

Amazing! A public works project ahead of schedule! But it's a great thing to finally have this new major artery complete as it's been a long time coming, met many roadblocks along the way. The result is expected to be less cut-through traffic into Pleasanton on First St/Stanley, Bernal/Vineyard, Valley/Stanley as this Hwy 84/Isabel will provide communters living in San Joaquin Valley a short-cut to 580 both am and pm trips. The extension of Stoneridge Drive was contigent on getting this Hwy 84/Isabel connection completed as two council members would not support the extension of Stoneridge unless this project was funded. Maybe now, finally, traffic will be more balanced and evenly distributed around the Tri-Valley, diminshing he cut-through traffic in our town. May take some time however for driver behavior to change.

Ruth, drop the 'maybe'. Those two mean, selfish, council stallers, should have Stoneridge ready to open next month. We should be at their front doors next week, if it's not opening before Christmas. No more excuses allowed ! Time is up ! Jan rains will not be an allowable excuse, work 24 hrs and beat the rains !

The Isabel exchange is only one piece of the regional transportation improvements that need to be made in order to reduce cut-through traffic through Pleasanton. We still need Hwy 84 between 680 and Pigeon Pass to be widened. Stoneridge Dr. was being used as a game piece in order to get that needed improvement on 84 while pulling the Hwy 84 improvement was used as punishment for not building the Stoneridge Dr. extension.

Yup, my fears were confirmed today. It was in today's Valley Times that after this interchange is completed then CalTrans is going to embark on widening Isabel. They just did a big revamp of Isabel a few years ago and only made it two lanes wide. Now they are going to spend millions to widen it to 4 lanes. Why in the he** didn't they make it 4 lanes when they did the revamp a few years ago. This is a classic case of penny wise, pound foolish operations.

Q. Why do they want to spend money to close the Murrietta on ramp going west?
Please: Can some one let me know how to get on now?

? Why are they closing a perfectly good overpass, Highway 580 and West Portola Ave. It makes NO sense. It will help with the traffic on 580/Isabel. Please explain. Thanks.

Apparently there is a minimum distance requirement between on and off ramps and Portola/Isabel would be too close for safe merging.

HIGHWAY 84 has been on the books for a LONG TIME. I'd heard years ago that the reason it wasn't made 4 lanes (like it was supposed to have been) was because of the little bridge just before crossing Vineyard. Now that lots more people are using 84 to get to 680, the backup is telling them, it's time. Most of the road seems to be wide enough to accomodate 4 traffic lanes except for a couple of spots. BUT HEY - aren't they additional jobs we are providing for people that would otherwise be out of work?
As for the Stoneridge extension - HEAD 'em UP - MOVE 'em OUT and GET IT GOING PLEASE !!! Make it easier to get around our little congested town. THANK YOU.

Get over it and just enjoy the new overpass-It was great today heading out to the college from Isabel. No need to sit in traffic with all the soccer moms going to and from costco. Took me less then 10 minutes to get back to my house in P-town from the college. It used to take a hour at times.
