Eyes on the Street: When Will the Bike Box Reappear on Scott Street?
Andy Thornley of the San Francisco Bicycle Coalition points out they're not full bike boxes. In the case of Scott, it's really a quarter bike box, and a half bike box on 14th:
A full bike box would look like those in Portland, with colored pavement in the box (as well as color in the bike lane feeding in, and, if appropriate, color in the "receiving" bike lane on the far side of the intersection), "STOP HERE" marked on the pavement before the advance stop line, and a public education program to let everyone know what they are and how they're meant to be used.
Thornley explained the two bike boxes in San Francisco are an experiment, but it's unclear whether the MTA has any plans to turn them into full, colored bike boxes, or add more, once the injunction is lifted:
In MTA's earlier request to experiment with color in bike right-of-way, bike boxes had been one of the senses to test, but I see that the final list of application senses approved by the Federal Highway Administration no longer includes bike boxes. That is, even after going through the years-long and hyper-mannered dance of official experimentation (which had led the sanctioned use of color off into a very limited scope already) the MTA still won't have made any productive codification of color for bike boxes, let alone "ordinary" continuous bike lanes, as experienced in much of the rest of the civilized world.
We've got a request into MTA spokesperson Judson True for more information. We'll post an update as soon as we hear back.
Update: MTA spokesperson Judson True says the bike box will be repainted next week. "That was the plan all along."
As for colored bike boxes, the MTA does plan to experiment with those "in the next couple of years."
