The northbound lanes of 19th Avenue between Sloat Boulevard and Lincoln Way are going to start being repaved as of Monday, December 1. And this means for the second time in five years, this section of Highway 1 through San Francisco will see some increased traffic due to lane closures and roadwork. As NBC Bay Area reports, the repaving work begins on the northbound side of this six-lane thoroughfare, at Sloat Boulevard, proceeding north up to Golden Gate Park.
