Limekiln Creek Bridge Replacement

Project Description

Caltrans proposes to replace the existing concrete Limekiln Creek Bridge in Monterey County on Highway 1 near Lucia. Within the limits of the proposed project, Highway 1 is a two-lane undivided highway with two 10- to 12-foot lanes and 0- to 4-foot non-standard shoulders. The proposed project lies exclusively within the Limekiln State Park property. The entrance to Limekiln State Park is directly off the highway at the southern abutment of the bridge. There is also access to the beach from Limekiln State Park underneath the Limekiln Creek Bridge. The existing bridge consists of eight piers and two abutments and is approximately 580 feet long and experiencing deterioration.

Project Benefits

Purpose

The purpose of the project is to ensure the reliability of Highway 1 for the traveling public, support the movement of essential goods and services, and maintain coastal access along this section of the Big Sur coast by addressing chloride intrusion in Limekiln Creek Bridge and slope stability problems.

Need

The project is needed due to chloride intrusion in the concrete of Limekiln Creek Bridge, which was confirmed with concrete core testing and inspections by Caltrans’ Structure Maintenance and Investigations Team in 2012. There has been irreversible damage to the superstructure and substructure elements caused by chloride intrusion from pervasive salt-laden fog. This has resulted in frequent concrete cracking and reinforced steel and cable corrosion. There have also been recurring slope stability problems at the north abutment caused by powerful waves. There have been attempts to stabilize this slope; however, it is not possible to permanently stabilize it. There is a permit requirement (Coastal Development Permit 3-09-020) from the California Coastal Commission to remove the existing slope armoring. As a result of these issues, the need for replacing the existing bridge was identified by the Structure Maintenance and Investigations peer review committee in its October 2012 meeting.
