  • Phase 3: 16 weekend closures between La Brea and Highland avenues. Traffic will be detoured via 6th St. and Highland or 6th Street and La Brea.

The closures will allow Metro to begin excavating a portion of Wilshire Boulevard and replace it with concrete deck panels so traffic can continue on the street amid the excavation work. Different portions of Wilshire will be closed for the next 22 weekends, except during Fourth of July and Labor Day weekends.
