Paint-Happy MTA Crews Prepare for Physically Separated Market St Lane

Though it might sound incredible to San Franciscans who have followed bicycle issues for the past three years, not only are more bicycle infrastructure improvements coming, they might be better than anyone imagined. Streetsblog has learned that in addition to the lanes striped today on Mississippi and Howard and seven more bike lanes expected in the next few weeks, the MTA will install a separated bike lane on Market Street.

At a press conference tomorrow, Mayor Gavin Newsom and MTA officials will announce a number of "innovate design treatments" allowed under a judge’s order issued last week, including plans to install safe-hit posts on an existing bike lane creating a physically separated lane on Market between 9th and 10th Streets. The posts are similar to the ones now in place in the bike lane at Market and Octavia. It was still unclear, however, if the project would include both east and westbound bike lanes, or just one.

"San Francisco’s first attempt at a physically separated bike lane is a really great step forward. Separated bike lanes are a great way to get novice cyclists who are uncomfortable riding in traffic more used to riding on the street," said Marc Caswell, the SFBC’s program manager. He said the SF bike lane will be similar to early physically separated bike lanes in New York City, which were improved under Janette Sadik-Kahn, Commissioner of the NYCDOT.

The protected bike lane will help eliminate conflicts between drivers and bicycle riders on that portion of Market Street where drivers often fail to respect the bike lanes. "A physically separated bike lane is a great way to make sure the bike lane is a clear and safe way to travel without any obstructions," Caswell said.

Tomorrow’s press event, expected to be attended by several other electeds and the SF Bike Coalition, will culminate with the painting of a green bike box on Scott Street at Oak, which is believed to be the first green bike box in California, according to the MTA. In addition, tomorrow DPT crews will install bike lanes on Beale and Kansas Streets, paint sharrows on Hayes Street and begin three days of sharrow painting on 5th Street from Market Street to the freeway, according to the MTA’s Bridget Smith, head of the agency’s Livable Streets implementation program.

Earlier today, crews installed a bike lane next to the right-turn lane on Howard Street at 9th, which has been a trouble spot for bicyclists. They also installed two blocks of bike lanes on Mississippi Street between 16th and Mariposa near the Guardian building. Crews did not have time today to paint bike symbols in the lanes, but that work will be completed tomorrow, according to Smith.

The DPT crew on Mississippi Street was jovial and excited to be installing the city’s first major bike improvements in awhile. It took them a few hours to complete the work, using a tension rope to first mark the stripes, and then rolling over the mark with a striping machine that releases warm thermoplastic that dries in thirty seconds. A DPT worker then follows, sprinkling glass beads over the thermoplastic and wham, there’s your bike lane! 

The latest work followed Tuesday’s installation of the city’s first bike lane in three years, a left-turn bike lane on Scott Street between Oak and Fell on The Wiggle.

  • “rough pavement” on Mississippi? That’s like saying Afghanistan has “minor security issues”.

    I find amusing that two of the first lanes that go in will suffer some usage issues. Used to be a large percentage of users take a left onto Fell from Scott sort of via the sidewalk and definitely against the red. Some of that will still happen (commenter on other thread apparently went out and did his own survey – wish I had that freetime…).

    Mississipi is weirder. The lane goes from Mariposa to 16th. Almost all the bike traffic in Potrero Hill goes down 17th. 17th to Mississippi, then left on 18th. Mariposa from the Dogpatch, right on Mississippi, left on 17th. In order to do so, it’s best to merge over and take the lane to establish your left turn as soon as possible, especially going from Mariposa to 17th because the auto traffic tends to go straight to 16th.

    This is not an obscure route – it is the silk route from 22nd St Caltrain to the Mission.

  • Did not put in my final point re:Mississippi. With a bike lane in place, I worry that auto traffic might be aggreived by cyclists taking the lane to position for the left.

  • Awesome. Fantastic. Great!

    This is wonderful news! It is long overdue, and amazing to see the city respond so quickly with paint on the ground.

    I wonder about that physically separated bike lane on Market between 9th and 10th – I ride that way every day, and in the mornings (eastbound) there are often so many cyclists bunched up at the light at 10th, that it’s a mini mass that just doesn’t fit in the bike lane and spills out into the driving lane. There are so many bikes some mornings that cars just have to wait their turn! So while a physically separated lane is great, it might make it harder to fit all the cyclists? Or maybe that’s why they’re putting it there – to keep the roadway clear for cars?

    I’d love to see separation westbound too. There are often cars parked there, or delivery trucks.

    Alleluia!!! And thanks to everyone for a lot of work to make sure this happened. Thank you Streetsblog for spreading the news. Hope to see lots of people Thursday at 1pm for the official unveiling of the city’s first colored bike box & the first new bike lane striped in quite a while. Cheers to the City for the fast work since the Judge’s ruling — it’s thrilling to see so much change on the ground so quickly

  • i super heart howard st.

    I’ll be damned. If the physically separated bike lane happens, even if it’s just for one block, that will be significant.

    john and yangmusa — yeah, just slapping down bike lanes where it’s pretty easy to do so is NOT some kind of amazing thing. why are so many people happy about this? the better improvement would be to lower speed limits, time traffic lights for slower speeds, put in bike boxes all over, convert one-way couplets, institute a minimum 5-ft separation for cars passing bikes… All of these things are “easily reversible” btw

    I heard that the bike box on Scott was supposed to be painted yesterday, but Newsom couldn’t make it for his photo op, is there any credibility to that rumor?

  • Yeah, I saw that also. I was hoping it was a bad Newsom joke, but I have a sinking feeling it isn’t.

  • Virginia Lee

    it’s true, the painting was rescheduled for newsom.

    “..kick-ass DPT striping crew” Ha Ha Ha what a joke


SF Gets First Protected Bike Lane! Drivers Already Violating It

DPT crews installed San Francisco’s first physically separated bike lane this morning on a westbound stretch of an existing bike lane on Market Street between 9th and 10th, and before workers had even finished putting in the final safe-hit post, some drivers […]

Fell Street Arco Bike Lane Might See Improvements Soon

Click to enlarge. Proposed changes to Fell St. bike lane, soft-hit posts in red. The MTA might have a solution for the dangerous conditions at the Fell Street Arco gas station, where motorists queueing up to buy gas routinely block the bike lane and force cyclists to navigate between bumpers or try their hand a […]
