Weekend commute warning for Sherman Oaks drivers: Southbound I-405 lane reductions run July 24–27

Caltrans is scheduling extended weekend lane reductions on southbound I-405 through the Sepulveda Pass that will affect traffic in and around Sherman Oaks. From 10 p.m. Friday, July 24, 2026 to 5 a.m. Monday, July 27, 2026, southbound I-405 will be reduced to two lanes through the U.S. 101 connectors, with multiple ramp and connector closures.

Patch specifically notes the two-lane reduction in the area of the 101 Freeway in Sherman Oaks. The result: less roadway capacity overnight and on Saturday and Sunday, plus detours for trips involving the closed connectors.

What’s changing on southbound I-405 (July 24–27)

During the work window, Caltrans says:

• Southbound I-405 reduced to two lanes through the U.S. 101 connectors
• Burbank Boulevard on-ramp to southbound I-405 closed
• Northbound I-405 off-ramp to Getty Center Drive closed
• Northbound U.S. 101 connector to southbound I-405 closed

Northbound I-405 is described by Caltrans as not being impacted by lane reductions, but drivers still need to account for the connector/off-ramp closures listed above. Even if your car is going north, these closures can shape traffic patterns around the interchanges.

Detour for northbound U.S. 101 → southbound I-405

Caltrans provides a specific reroute for drivers who normally use the closed northbound U.S. 101 connector to reach southbound I-405:

• Exit northbound U.S. 101 at the Sepulveda Boulevard off-ramp
• Head south on Sepulveda Boulevard
• Use the Sepulveda Boulevard on-ramp to get onto southbound I-405

Drivers who rely on regular connector access points (especially overnight and early-morning commuters) may want to pre-plan this detour before leaving home.

Why Sherman Oaks drivers should plan ahead

With southbound I-405 operating at reduced capacity through the U.S. 101 connectors, delays can spill over beyond the exact lane-reduction segment—particularly when ramps and connectors are closed. Businesses with deliveries, parents coordinating school-time schedules, and anyone commuting between the Westside and the San Fernando Valley may find that normal travel times don’t hold up as reliably during the weekend window.

Caltrans also reminds drivers that construction schedules can shift due to weather or operational needs, including changes to closure times, lanes closed, and other details.

Check before you drive: Quickmap and current conditions

Caltrans directs drivers to confirm real-time impacts using Caltrans Quickmap. Caltrans’ Road Information page for I-405 is also intended to help residents verify current conditions as the weekend progresses.

If you’re traveling southbound I-405 through the Sherman Oaks area this weekend, plan for tighter capacity and verify the latest closures shortly before departure.
