launch  of the traffic diversion pilot program on Market, which has required eastbound private automobiles to turn right off of Market at 6th and 8th Streets.
The trial has largely been praised by bicyclists and has helped Muni buses travel down the street an average of 50 seconds faster , but the intersection of Market and 8th Streets has been a challenge for cyclists from the start. There's no bike lane at the intersection, and cars queuing up to turn right leave little room for bikes, which are hemmed in by a Muni boarding island. The MTA hopes 10th Street will have fewer conflicts, since it has a separate bike lane, made possible by the lack of a Muni boarding island, and fewer pedestrians, partially since it's farther from a Muni Metro station.
The right-turn-only requirement will switch from 8th Street to 10th Street on January 26, and will be in place for at least six weeks, at which point the city will evaluate the impact of the change. The MTA first announced  it was considering the change two months ago. At the time, MTA Chief of Staff Debra Johnson said the agency also believed the directed turn would be easier to enforce at 10th Street than at 8th Street.
MTA Executive Director Nat Ford described the change as a gain for Muni riders as well.
"This pilot project takes a measured approach to improving conditions for transit customers and pedestrians," Ford said in a release. "Adjusting the pilot will provide us with additional information to shape our collective decisions about Market Street's future."
Kit Hodge, Director of the Great Streets Project , welcomed the change as a sign of the city's commitment to learning from the trial - which is part of a broader effort to improve Market Street . "We're pleased the city has been evaluating the project and that they're paying attention to refining the trials and thinking about next steps," said Hodge. "The important thing is this has been an iterative process, and this is proof that the city is really thinking about refining, putting out meaningful trials, and producing something on the street that actually improves conditions for everyone."
