Caltrans District 5 is preparing to proceed with the Quigil Viaduct Permanent Restoration project to replace a damaged retaining wall near Lucia in Monterey County, approximately 0.1 miles south of the Limekiln Creek Bridge. The area suffered extensive landslides, embankment failures, and debris flows due to prolonged heavy rains and storms between December 2022 and January 2023, which compromised the highway and required emergency stabilization measures. This project will construct a permanent viaduct to address the structural vulnerabilities caused by saturated ground conditions and to eliminate reliance on temporary repairs. It will also include upgrades to existing guardrails to meet current MASH safety standards, enhancing long-term roadway resilience and public safety. The project is forecasted to be posted on May 27, 2026, with Lucas Marsalek, Senior Environmental Scientist, listed as the primary point of contact for inquiries.

Full Description

Show more
The purpose of the project is to construct a viaduct to replace damaged but temporarily stabilized retaining wall under an emergency contract. The project is needed to construct a viaduct and upgrade existing guardrail locations to comply with MASH standards. The project is in Monterey County, near Lucia, at 0.1 miles south of the Limekiln Creek Bridge. The combination of saturated ground along with continued heavy rain and winds from the multiple large rainstorm events from December 2022 through January 2023, resulted in multiple landslides, embankment failure, and debris flows which directly impacted the highway and its related systems. Emergency repairs were done to restore essential traffic, minimize the extent of existing damage and protect the remaining roadway. This project intends to provide a more permanent solution.
