A two-week trial to reduce automobile traffic lanes from four to three on Market Street and JFK Boulevard, between 15th and 20th streets, to allow for bicycle lanes, did not hamper either parking nor loading and deliveries, the Mayor's Office of Transportation and Utilities said yesterday.

"The trial has demonstrated that it's worth continuing to explore options for transforming Market Street and JFK west of City Hall into truly complete streets: streets that well serve pedestrians, buses, cars, delivery vehicles and bikes," said Rina Cutler, the deputy mayor for Transportation and Utilities.

The trial was a joint project of the transportation office and the Center City District, which began working with building managers and property owners on the proposal restructuring of traffic lanes in 2009.
