According to the California Department of Transportation, southbound Topanga Canyon Boulevard from Rodeo Grounds Lane (TB 630 D6) to Pacific Coast Highway (SR-1) on Tuesday, March 18 will be closed due to the installing of a sign structure that is being set at the intersection of SR-1 and SR-27.
Also subject to closure for two hours sometime between 8 p.m. to 5 a.m. is southbound SR-27. The closure expects to occur during the night but motorists are encouraged to an alternate route if they want to go onto PCH.
However, PCH to northbound SR-27 will be open to motorists through the night.
