Eyes on the Street: Why Bike Lanes Need Protection

Why is it so important for bike lanes to have physical separation from traffic? Because without it, you never know when a two-ton metal box is going to fly across your path.

The photo above was snapped on 59th Street between First Avenue and Second Avenue and posted to Twitter by Dirk Peters last night. If those Jersey barriers weren’t there to protect the westbound bike lane, this might not have turned into a story about bike lane design — it could have been about someone on a bike getting seriously injured.

Meanwhile, on West Street in Greenpoint, where the Department of Design and Construction has installed seven blocks of the Brooklyn Waterfront Greenway, you can see the other downside to going without protection: Motorists turn the bike lane into a parking lot.

The bike path is in serious need of physical barriers, judging by these photos that Doug Gordon posted on Twitter earlier this week. Between Noble Street and Milton Street, the entire path was filled with parked cars.

There was some of that going on when I visited the site in January, but it was mostly contained to one or two blocks. That is no longer the case:

Clearly, motorists abhor a vacuum.

The design here called for a mountable curb but no other physical separation. That’s not going to be enough. To make this section of the greenway a viable bike path, Jersey barriers, heavy planters, or some other form of protection will be needed.

    Mountable curbs are a ridiculous design. When the very design makes it easy to drive a car on the bike lane, it is any surprise when people do? SF has had the EXACT same problems with this design:

    Pouring a raised curb over that buffer space, a la South Street, should be the absolute minimum treatment.

    Besides physical protection being necessary for this portion on West Street, DOT should look at continuing the two way protected bike lane on Kent Ave north on the west side of Franklin Street to Quay Street in order to connect with the West Street Greenway.

  • Joe R.

    Not sure the “soft hit” posts are any better. Real protection consists of something which will physically damage or destroy motor vehicles if they go where they’re not supposed to go. At a minimum protection should consist of deeply buried bollards spaced no further than 5′ apart. Jersey barriers or strong fences are even better.

    Why don’t they just put a towing bounty and fine on the cars parked there?

  • J

    Yeah, I wasn’t advocating for soft-hit posts, and I completely agree that more substantial protection is needed.

  • ItsEasyBeingGreen

    Are they not already connecting this to Kent? It would be ridiculous if they didn’t.

  • Max

    There’s already the on street bike lanes there between moving traffic and parked cars, not protected. This would cause northbound cyclists to cross Kent/Franklin twice in order to access the West St Greenway, as opposed to keeping cyclists on the west side of Franklin, which would reduce conflicts.

  • ahwr

    You don’t think think there would be lots of crashes if you switched to a regular curb at some point?

  • ItsEasyBeingGreen

    Mountable on the bike side is good, mountable on the car side is bad. Ideally there would be a curb in between the bike path and the street that is higher than both. Cycletracks protected by elevation only don’t seem to work very well without exceptionally well behaved drivers (Denmark?). Even with a curb in between it might be necessary to add bollards in some locations.

  • AnoNYC

    Closely set flexible barriers or the hard plastic ones are pretty effective. Too wide though and drivers squeeze into the restricted area.

    Bollards or planters are the best for protection from an out of control vehicle.

    Overall, painted lanes in this city have been a failure, they need physical protection.

    Hah! Whatever will people weaving errantly in and out of bike lanes do???

Eyes on the Street: The Case of the Missing Bike Lanes

The streets have been repaved. Lane striping, crosswalks, and stop bars have been added back. But there’s something missing from two streets in DOT’s bike network: bike lanes. In Williamsburg, Driggs Avenue has been repaved — but you would never know it’s a key bike connection from the Williamsburg Bridge. The street has all its stripes back except […]

DOT Floats Greenwich Avenue Protected Bike Lane to Manhattan CB 2

DOT may create a safer cycling connection between Sixth Avenue and Eighth Avenue with a two-way parking protected bike lane on most of Greenwich Avenue — if Manhattan Community Board 2 votes for it. Greenwich is a short street but an important east-west connection in an area where the Manhattan grid breaks down. Even though there is […]

The Case for a Two-Way Protected Bike Lane on Plaza Street

Cross-posted from Brooklyn Spoke. In April 2010, DOT proposed an overhaul of the chaotic and dangerous Grand Army Plaza to include two-way protected bike lanes on Plaza Street East and West. (Plaza Street is not the high-speed roadway around the arch and fountain, but rather the less trafficked outer roadways, which already have one-way buffered […]
