Eyes on the Street: Remove Car Parking, and Bike Lanes Vastly Improve

Despite the utility ditch, do parts of the Valencia bike lane actually feel safer with the parked cars removed? Photos: Aaron Bialick

In most of San Francisco’s bike lanes, people are forced to ride between parked cars and moving cars. The looming threat of opening car doors and cars entering the bike lane is unsettling enough to keep many San Franciscans from riding a bike at all.

But take the car parking out of the equation, and that same 5- or 6-foot wide bike lane can feel immensely safer. That difference is apparent at construction sites like the current one at 1844 Market Street, between Octavia Boulevard and Laguna Street, where the north-side parking lane has been replaced by a fence separating the walkway and the bike lane. Suddenly, climbing the hill towards the Wiggle has become a less harrowing experience — at least until the parking comes back.

At another construction site, half of the northbound bike lane on Valencia Street underneath the Central Freeway was recently occupied by a utility ditch, with the bike lane running along the pavement’s remaining edge. Parts of the parking lane are closed to drivers. This case is probably more subjective to the rider, but I actually felt better riding in a skinnier bike lane along the edge of a small cliff compared to riding in between cars (the space occupied by the ditch is normally the door zone, anyway).

It goes to show how a bike lane’s quality can vary widely based on something as simple as its alignment. Even without physical separation from motor traffic, I would hazard that a bike lane striped along a curb feels comfortable for a much broader demographic than one placed in the door-zone.

Take some recent examples of new bike lanes in San Francisco: the buffered bike lane on Eighth Street is about 11 feet wide, but because it’s subject to frequent incursions by cars (and runs on a street with heavy motor traffic), it certainly doesn’t feel like a dedicated space safe enough for anyone 8 to 80 years old. (There is a long-term plan to convert it to a parking-protected bike lane.)

Meanwhile, parts of the new bike lanes on 17th and 23rd Streets are curbside. Perhaps Streetsblog commenters who use them can attest: How does your bicycling experience change when you don’t ride next to the door zone?

The new bike lanes on either side of 23rd Street may be the same width, but they're not equally safe. Photo: ##http://www.flickr.com/photos/sfbike/7544987556/##SFBC/Flickr##

What About Bike Safety During Paving and Construction Projects?

Streetsblog tipster Dan Crosby brought this to our attention: due to road work on San Jose, the intersections with Guerrero and Dolores are even more confusing and dangerous for people on bikes. From Crosby’s email to Streetsblog: There’s been some major (and much-needed) repaving work done recently on San Jose and Guerrero, between Cesar Chavez and […]

Will SFMTA Make its Deadlines for Protected Bike Lanes?

Recently, District 8 Supervisor Jeff Sheehy committed to protected bike lanes in his district from Octavia to Duboce on Market, as part of the Upper Market Street Safety project. But despite Sheehy’s support, the San Francisco Municipal Transportation Agency (SFMTA) leadership delayed a key hearing and, according to a report in the SF Examiner, the protected bike lanes were […]

Eyes on the Streets: Upper Market and Turk Finally Get their Protected Bike Lanes

During Construction, the Safety of People on Bikes Is Dispensable

We recently wrote about the benefits to bicycle riders that come from temporarily removing car parking at construction sites. But there are other times when construction can do just the opposite, throwing them into harm’s way. At the very same construction site at 1844 Market Street, where we pointed out that parking removal had improved […]
