Two traffic enforcers oversee the start of a two-week dry run of the zipper lane along the northbound portion of Katipunan Avenue in Quezon City on Thursday (Sept. 21, 2023). The objective of the zipper lane is to use the excess capacity of the southbound direction of Katipunan Avenue after the intersection in front of Ateneo de Manila University Gate 3 from 6:30 a.m. to 8 a.m. to ease the heavy traffic in the area. (PNA photo by Joey O.
