Starting Tuesday, the south bike-ped path of the Williamsburg Bridge will be closed for resurfacing and other improvements. The changes on the way will introduce new markings, reducing conflicts between cyclists and pedestrians by separating bike and foot traffic into different lanes.

Users will be re-routed to the north path until the first phase of work is completed. Crews will then move to the north path as users are directed to the south. The full construction timeline is unknown at this point.

Also tomorrow, Transportation Alternatives will be surveying cyclists on the Manhattan side about the routes they take once they get off the bridge. How many people keep riding straight on Delancey Street, and how many are using the first available side street?

With DOT adding new bike routes on side streets in an attempt to divert cyclists from dangerous Delancey, the survey could provide useful before-and-after data, said TA’s Caroline Samponaro. The lanes on Suffolk, Rivington, and Stanton are slated for striping later this spring. "If people are continuing to ride on Delancey," Samponaro asked, " what does that mean?"

You can take the survey at the Manhattan base of the bridge from 7 to 10 a.m. tomorrow.
