Quigil Viaduct Permanent Restoration

The Quigil Viaduct Permanent Restoration project, managed by Caltrans District 5, involves the construction of a viaduct and the replacement of guardrails on State Route 1 in Monterey County. Located near the community of Lucia, approximately 0.1 miles south of the Limekiln Creek Bridge, the project serves as a permanent solution to address damage caused by landslides, embankment failures, and debris flows resulting from severe rainstorms between December 2022 and January 2023. The primary objectives are structural stabilization, modernization, and ensuring all guardrail locations comply with Manual for Assessing Safety Hardware (MASH) standards. The scope of work is strictly limited to safety upgrades and the restoration of the existing structure; it does not include expanding vehicular capacity, adding new travel lanes, or changing the overall function of the highway. This project is classified under NAICS code 237310. Administrative oversight is provided by Senior Environmental Scientist Lucas Marsalek, and the project has been granted a Notice of Exemption as it focuses on safety and modernization within the existing highway footprint.
