Southbound Highway 101 Bypass Lane Installed in Ventura County

Source: Caltrans

The California Department of Transportation (Caltrans) plans to install a southbound bypass lane on U.S. 101 near Mussel Shoals that crosses over the median to the left northbound lane and it will extend more than four miles to Faria Beach. The bypass lane will be protected by k-rails to avoid northbound traffic, no exits will be available in the corridor and the configuration will remain in place from about 11 p.m. April 22, 2022, to January 2023. Motorists can expect delays.

The purpose is to complete pavement rehabilitation on the two right lanes and shoulder of southbound U.S. 101 from Mussel Shoals to Faria Beach, a 4.3-mile work zone. The left southbound lane will remain open on the coastal side of U.S. 101 with access to the off- and on-ramps at Seacliff. Ramp closures will occur 9 a.m. to 3 p.m. Wednesday, April 27, and Thursday, April 28, as well as at intermittent times during project.

Other factors include:

  • Two right northbound lanes will remain open from Faria Beach to Mussel Shoals.

  • The speed limit is reduced in the work zone to 55 miles per hour with fines double for violations.

  • When work is completed on the southbound lanes, a similar northbound bypass lane will be installed for an additional nine months to complete pavement rehabilitation on the two right northbound lanes of U.S. 101.


All work is subject to change due to weather or construction-related issues. Residents and businesses located near the freeway may experience noise, vibrations and dust associated with construction activities. Detour signs will be posted. Real-time traffic information can be found at

The work is included in the U.S. 101 Pavement Rehabilitation, a $48 million project that includes $5.5 million in funding from Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017. Completion is expected in the winter of 2023/2024. For more information, go to:
