In other bike lane news around the country:
- Kansas City, Missouri, now has two bridges with separated and protected bike lanes. A concrete barrier separates a combined walking and biking path from traffic.
- Chicago’s door lane network grows a little more with new door lanes on Grand Avenue and Illinois Street. Downtown is in the most need of bike lanes so these should be useful (although I advocate for ones going through the Loop).
- Separated bike lanes again under attack in New York City, this time on Columbus Avenue. It was only installed in August.
- Washington, D.C., installed bike boxes and contraflow bike lanes (in August 2010) on a diagonal street at a six-way intersection (we have tons of six-way intersections in Chicago). John Allen, notable for his stance on bikeways and how they conflict with traffic engineering principles, approves of the design. In theory, contraflow bike lanes next to parallel parking lanes are good (and better than door lanes) because (1) the door to open is the passenger’s door, which opens less often than the driver’s door; (2) the person opening the door and the person riding the bike are staring at each other; and (3) if a person riding a bike collides with the door from the oncoming direction, the collision should be less damaging Â to the person riding the bike. (You can thank former Mayor Adrian Fenty and former transportation commissioner Gabe Klein, and their staff, for these improvements to the bikeway network.)
The new door lanes in Chicago on Grand Avenue (as well as Illinois Street) involved a road diet, the narrowing or removal of main traffic lanes. You can see how a lane was removed – the stripes demarcating the two lanes have been ground out. This may reduce traffic speed and reduce confusion and collisions, a welcomed change. Watch a video of the bike lane striping being applied.
In Washington, D.C., a unique and adapted bike lane design for a diagonal street where it crosses two other streets at a six-way intersection. Another way to demonstrate what a bicycle lane could do.
