Caltrans will be closing large portions of 19th Avenue on two upcoming weekends. The next closure begins on Friday, May 8. Closures begin at 7 a.m. on Fridays, which may impact school drop-off and pickup traffic, in addition to weekend travel. Students, families, and staff should expect major delays and detours, and plan for significantly increased travel time, especially for school commutes, activities, and weekend events.
