Thanks to Streets Forward<\/a> for its help with this piece.<\/p>\n

Part of Polk Street <\/a>was closed for the Pride Parade last weekend. But in doing so, the city once again blocked off a protected bike lane and created no safe detour.<\/p>\n

Streetsblog reported just last week that the Moscone Center had once again closed off the Howard Street protected bike lane, this time for the Config Global Design conference<\/a>. The only thing even resembling a detour was a sign that said \u201cdetour.\u201d An SFMTA spokesperson said the agency would look into it and respond, but they never did.<\/p>\n

The root problem is that SFMTA\u2019s street-closure process\/application simply doesn\u2019t require protecting people on bikes. SFMTA\u2019s application<\/a> for an event requires consideration of everything from disability parking to fire safety. But the only mention of anything for bicycling is: \u201cEncourage attendees to ride bikes or take public transit [\u2026] You may want to add an area for monitored bicycle parking to your plans.\u201d<\/p>\n

Things are a little better in SFMTA\u2019s \u201cBlue Book\u201d for street construction<\/a>, which has an entire section on \u201cworking on bicycle routes\u201d that includes requirements to provide alternatives, mostly for painted lanes. But it doesn\u2019t address proper detours for separated or protected bike lanes (Class IV) such as on Howard, Polk, Valencia, and other streets.<\/p>\n

Unfortunately<\/a>, this has been a known problem in San Francisco for years<\/a>.\u00a0<\/p>\n

The Netherlands or Denmark<\/a> have requirements to set up protected bike lane detours during road works and construction. Even that faraway city called Oakland<\/a> occasionally gets this right. Denver\u2019s Special Event Permit Process<\/a> requires \u201cA detour plan shall be required when closing a roadway, a bike lane or a sidewalk\u201d and \u201cbike lanes on collector\/arterial streets must be detoured to the nearest like street with a bike lane\u201d and even and even recommends avoiding \u201crequesting a closure for a collector\/arterial roadway during \u201cPeak Hours\u201d and avoid disruptions to the bus lanes and bike lanes.\u201d NYCDOT proactively installs temporary detours on adjacent streets a week in advance of major recurring events (not that they always get it right either<\/a>).<\/p>\n

Temporary measures are not that hard to do: it just requires some signs, temporary plastic<\/a> or concrete Jersey barriers<\/a>, and a little thought for the safety of bicyclists. But first, SFMTA has to actually add an official guideline for protected bike lanes in its regulations. Mayor Daniel Lurie could expand his Street Safety Initiative<\/a> to direct SFMTA to incorporate detour requirements for protected bike lanes for permitted events.<\/p>\n

Hosting events on our streets is important, and construction and maintenance require street closures. But construction and events happen all the time. If the city doesn\u2019t require safe, protected detours for people on bikes, they will continually be put in danger, even on streets with hard-fought-for protected bike lanes<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"Thanks to Streets Forward for its help with this piece.
