New and Improved? The 2016-Era Speedbumps on JFK Drive in Golden Gate Park Now Have More Painted Lines

Monday, April 17th, 2017

So these lines are new, that’s the news.

I’ve never seen this kind of thing. I guess people were getting surprised by the bumps?

Frisco remains on the cutting edge of paint engineering, it would seem.

I’ll tell you, I go over these things at a steady 25 MPH, but others slow down to about ten and then speed up again to around 30 only to slow down again a short stretch down the road. That’s the update…

Ever More “Speed Hump” Speed Bumps for Golden Gate Park – What’s the Recommended Speed for These Things?

Get up to “speed” here.

Here we go – on JFK looking east towards Transverse / Crossover

And now close to Marx Meadow looking west – this one will be going in soon:

I guess this one will go almost all the way across JFK Drive:

And, now closer to 30th Avenue, looking east – this was the first to be installed, now with a new sign:

I don’t know when I’ll make it back here with a vehicle. IMO, 20 MPH or so is prolly the limit for you. (I had my decidedly non-sporty ride mistakenly set in SPORT mode, but I don’t think it makes much difference on a road regularity as big as this, but I’ll try it again sometime on my ride’s softest suspension setting.)

OTOH, if you have a brand-new BMW M4 GTS, how about 0 MPH as the limit?

And on bikes heading west, IDK. Look out, Jack, is all I can say.

I think the actual speed limit for the bumps is 25 MPH, but that seems too fast for IRL.

Our SFMTA has reported that some drivers go 32-34 MPH on this stretch of JFK and I’m sure these numbers come from someplace real, but I’m also sure whatever stat they’d report has been manipulated for their own purposes, oh well.

On It Goes…
