Crews will demolish the center median of the Bolsa bridge as part of the freeway widening project.
This work will require a SB I-405 closure between Goldenwest Street and Bolsa, and NB I-405 will be reduced to three lanes between McFadden Avenue and Goldenwest Street.
The closures are set for 11 p.m. Friday, July 16, to 6 a.m. Saturday, July 17.
