The closure is the second of three weekend closures to repave 19th Avenue, also known as Highway 1. The first closure took place from April 24 to 27.

On Memorial Day weekend, both northbound and southbound lanes of 19th Avenue between Sloat Boulevard and Holloway Avenue will be closed from Friday, May 22 at 7 a.m. through Monday, May 25 at 10 a.m.

Officials said organizing the work over three weekends will reduce the impact to drivers from 40 days to 10 days.

Caltrans is also planning to repave the intersection of California Street and Park Presidio Boulevard this summer.
