The SFMTA is installing ladder crosswalks at intersections along the Wiggle.
By increasing the visibility of the pedestrian right-of-way, the new feel they bring even seems to calm bike and car traffic. The crosswalks should also assuage concerns  from those who say the growing number of bicycle commuters on the route makes the intersections less comfortable to walk across.
The improvements come along with green-backed sharrows  guiding bicycle riders, which crews have installed at three intersections and along Waller Street. The southbound lane of Steiner Street, where a crossing was striped connecting Duboce Park to Herman Street late last year, appears to be slated next, as the old sharrows have been ground off there.
