County installs new stop signs off Sunol Boulevard near Castlewood

Among key safety projects in works near freeway interchange

Alameda County officials have installed new stop signs to halt all drivers at the intersection where Sunol Boulevard splits off into Pleasanton-Sunol Road and Castlewood Drive just beyond the city limits in southwestern Pleasanton.

The traffic safety measure, which became active in the past couple weeks, was a mitigation effort developed after local residents raised concerns about unsafe conditions at the Y-intersection during previous community meetings Alameda County Supervisor Nate Miley hosted for residents of unincorporated Pleasanton.

"I appreciate Alameda County Public Works Agency staff's attention and dedication to improving the safety of vehicles and cyclists at this intersection," Miley told the Weekly.

"This road safety improvement project is a perfect example of residents bringing an everyday concern to a county department and my office, and then us taking collective action to resolve it," he said. "I look forward to continuing my work with Pleasanton, Happy Valley and Castlewood residents on other community matters."

The intersection, located between the Sunol Boulevard-Interstate 680 interchange and the Castlewood Country Club's Valley Course, typically sees increased traffic during commute hours as a popular cut-through route for drivers trying to avoid freeway backups.

Previously, the Y-intersection featured a single stop sign for eastbound Castlewood Drive traffic, with no stop for drivers continuing either way on Sunol Boulevard/Pleasanton-Sunol Road -- creating a tough line of sight for drivers trying to turn off Castlewood.

In response to the complaints, county public works crews conducted a traffic assessment of the area and determined adding stop signs to each direction on Sunol/Pleasanton-Sunol was the best strategy to address the concerns while minimizing vehicle backups along Castlewood Drive, according to Miley's office.

Installing the "all-way" stop at the intersection cost roughly $1,000, for parts and labor.

The county project isn't the only traffic safety improvement effort underway in the area notorious for commute backups, tricky sight-lines for drivers, and difficult conditions for cyclists and pedestrians.

Caltrans is in the middle of reworking the Sunol Boulevard onramp to northbound I-680 to install metering lights.

The city of Pleasanton has also been eyeing a $13.6 million project to redesign the Sunol/I-680 interchange to provide congestion relief, enhance operational safety and improve conditions for cyclists.

The project concept calls for signalizing the two intersections at the interchange and lengthening the existing merging lane from the southbound ramp to the freeway, among other changes, according to city officials.

The city is close to completing a project initiation document with Caltrans, a required step before moving forward with the preliminary analysis and environmental document phase. Once that report is approved by the state, the city can embark on full engineering design.

Refreshing to see a government official actually value and take residents concerns to heart. Thank you Nate Miley!
The city of Pleasanton City Manger and Engineering Director should take a page from his playbook, as all they seem to do well is ignore concerns and collect their bloated compensation packages.

Immediate response to increase traffic pain for commuters.
Don’t solve the problem, just compound it until we have no choice but to vote for fwy bond measures that deliver no improved means of transportation. Still can’t believe we don’t have variable flow traffic lanes by flow direction yet

Who stops for stop signs at T intersections anymore? Younger drivers consider it "uncool"

When my son and I "stopped" at the new intersection the other night we both thought the same thing, Who was the Moron.. Rhodes Scholar that came up with this bright idea. First, all this does is backs up traffic both on the roads and freeway/freeway off ramp. Second, this will be a money maker for the county through tickets (as they missed out on their last tax increase). The new intersection solves nothing, and fails at safety (having almost been rear ended while stopping). BTW, $1000 for some paint and a sign?

Good spot for a sign. I've never liked coming from Castlewood onto Sunol into Pleasanton. Lots of folks going 70 on Sunol into Pleasanton, and on that corner there is just not enough time to see them.

The bicyclists will be the very first violators of any improvements for everyone's safety. The arrogant fools will be running the stop signs ! Guaranteed ! And worst part is,they do it everywhere all the time and no one puts a stop to it ! No pun intended. Not to mention driving on the divider lines, failure to keep in the designated lane. Here us a good idea that law makers and those seeking safety should consider, LEGIBLE STATE ISSUED LICENSE PLATES FOR ALL BICYCLISTS WHO RIDE ON PUBLIC ROADS WITH THE REST OF US PRIVILEGED DRIVERS. Driving is a privilege, not a right. And law enforcement definitely needs to crackdown on arrogant, law breaking,, foolish bicyclists who have infiltrated the roads ! Never see the police issuing tix to BICYCLISTS ! Never !

AB, you do know cyclists have the same rights to the road (some exceptions like freeways) as cars/drivers? They are also bound by the same rules of the road. Cyclists also now have protection from cars of three feet around them. If there is debris on the road’s shoulder, most cyclists will try to stay on the stripe designating the right side of the road. So, you need to understand the rights of cyclists. And cyclists can’t say the rules of the road protect them and then ignore rules and stop signs.

Traffic engineers NEVER address the real problem and instead band-aid the issue to make it torture for anyone to go near the new congestion they intentionally created. Traffic engineers are about as dumb as they come!

Arrogant Cyclist sounds like the kind of person who would do a fly bye or clip a cyclist into the ditch and run. No room for you in this world. Be damned you wasted 5-10 seconds of your precious time to pass a cyclist. I for one, stop at signs and will be avoiding this new one anyways because that intersection is not really safe in the first place.
I'm not one of those car-free people.. so guess what? I pay the road tax already. I dont think you have thought the bicycle license through think the DMV is busy now or are you going to create a new dept of bicycles ?... anyways I'm all for tickets to law breaking cyclist and yes I have seen it done. You probably wrote your comment on your cell phone while driving :)
