Improved bike lanes the result of long but diligent effort

They could have made the bike lanes wider and safer by making the shoulder on the left side of the road narrower.

Very insightful write-up on how frustrating and bureaucratic the process is to get anything changed at all.
And a big "Thank You" for all the effort in getting at least something done at that very difficult and dangerous location.

However, this is in no way making this overpass "safe".

The paint is invisible from 280 Eastbound until cars are directly on it....and as evident from the photo, cars still cross it as they please.

In fact, I experienced on several occasions drivers appearing to confused and acting more unpredictable than before markings went down (when I would just claim the right lane on the bridge once there was a gap).

There needs to be at least some sort of signage implemented (e.g. "cyclists crossing"), and more important, a mandatory speed limit before the overpass and on the ramps.
Also, the traffic light at the WB off ramp (Golf Club) doing a nice job slowing traffic down, which significantly increases safety going WB.

I always feel that I take my life in my hands when riding across that overpass, particularly with the sun low on the horizon.

I'm glad to have more visible bike lanes here, but I am confused by the dashed and solid lines. In the EB direction, there is a very short dashed section, immediately before the exit to 280 N. (Image here: Web Link

My general understanding of dashed and solid lines is that one may cross dashed lines as long as it's safe, but that one may not cross solid lines unless absolutely necessary. If this is the case with the solid and dashed green bicycle lanes, then the dashed section isn't nearly long enough—or far enough in advance of the 280 exit—to allow vehicles coming from PV/Woodside to be able to get into the right lane and then exit to 280 N.

Is there a different rule applicable to dashed/solid green lanes than to other dashed/solid lines? I researched this question but wasn't able to find anything definitive. Based on the varied and unpredictable behavior I see when I commute down Sand Hill Road, it seems I'm not the only one who is confused by the new striping.

I hope someone can let us all know how we are supposed to drive through/around dashed/solid green lines. We need to make the streets safe for bicyclists, but this will only happen if drivers understand how they are supposed to behave!

I have been riding there for many years, and I think the changes are fantastic. It is much safer for everyone. Kudos to Don, Joe and the cyclist advocates that made this happen! Now if they could work on Page Mill....

@Menlo Cyclist - according to the Silicon Valley Bicycle Coalition, a safer Page Mill Road & I-280 bicycle route has been designed and funded, but the project has stalled because of a dispute between Caltrans and Santa Clara County. They have a petition to get it started again: Web Link

Anyone know the definitive answer to "wondering in woodside"'s question? I, and I am sure many others, am also confused as to when I can cross the bike path to get onto 280N. If it is only at the dashed line, then that is far to narrow for the automobile traffic to safely cross over to the 280N entrance. I believe that you can cross the double line any time it is safe, but you cannot come back over the double line until you come to the dashed line. Is that correct?

This is great news and I appreciate the clear explanation of the "chutes and ladders" involved in reaching the goal. May I ask if the same people could perhaps help to solve the Marsh Road/101 overcrossing? Many people from nearby neighborhoods (including me) would love to be able to bike safely to and from Bedwell Bayfront Park. Thanks.

What's missing: Connection from eastbound Sand Hill before the southbound onramp, to the bike lane leading to the overpass.

Having well marked bike lanes is very good

HOWEVER, as other people have commented, the dashed line section on the EB side is ridiculously short -- and creates a very dangerous car/bike situation

The dashed line section needs to be MUCH longer

As a bicycle pedestrian commissioner in Cupertino I know exactly how difficult making such changes is. The new markings are far superior and safer relative to what existed before. Kudos to all those involved in making this much needed improvement.
