The construction will take place through the Sepulveda Pass, closing northbound lanes between Getty Center Drive and the 101 Freeway. Full lane closures begin at 10 p.m., with a full northbound closure beginning at 12 a.m. and reopening at 5 a.m.
Sepulveda Boulevard will remain open during the closure times and will be used as a detour.
The bridge construction is expected to continue for a month, which may require additional closures.
