Quiguil Viaduct Permanent Restoration

Project Description

Quiguil was a place name recognized by the Mission San Antonio priests, and later by Gibson (1983:115) as a multi-village Salinan district. One known baptized person was from “las rancherías de Quiguil [the villages of Quiguil]”. Some references mentioned locations on the seashore, such as the “Mar por la parte de Quiguil [the portion of the sea shore in Quiguil]”, “Mar de Quiguil [the sea shore of Quiguil]”, and “Ranchería del Mar de Quiguil [the ranchería of the sea shore of Quiguil]”. (Milliken and Johnson 2005: 89)

The project name Quiguil was considered and selected in consultation with California Native American Coordinator Terry Joslin Azevedo and Patti Dutton, Salinan Tribe on Monterey and San Luis Obispo Counties. Quiguil is located in the Lopez Point Region, were Limekiln Creek is located.

Construction of a 180-foot-long viaduct with four-foot-wide shoulders will replace a damaged retaining wall. No tree removal or significant vegetation removal is proposed as part of the project. Approximately 225 feet of existing guardrail on the southbound side of the roadway will be replaced with guardrail that meets current safety standards. Approximately 225 feet of new guardrail will be placed on the southbound side of the roadway.  Options for rail type are being considered, including 86H and Type 85. There will be a soldier pile wall with timber lagging on the inland side of the roadway under the viaduct. Approximately 8.5 vertical feet and 180 horizontal feet of soldier pile wall will be above finish grade. No utility relocation is anticipated as there are no existing overhead utilities within the project limits. No shoulder widening is proposed as part of this project. Equipment needed to construct the viaduct include heavy machinery such as cranes, excavators, concrete mixers, and pile drivers. During construction, a reverse traffic control system will be implemented. One lane will be closed during construction of respective side of the viaduct. All work and staging will be done on the existing roadway and vehicle turnouts adjacent to the project site. The project will take approximately 350 working days, and night work is anticipated. The first stage of the project will move traffic to the northbound lane using one-way reversing traffic control and demolish the existing southbound lane. Once the southbound lane is demolished work will begin to build the southbound viaduct. The second stage will move traffic to the new southbound lane using one-way reversing traffic control, and construction will begin to demolish the existing northbound lane and begin to build the northbound viaduct. All work activities will take place within the Caltrans Right-of-Way.

 

 

Project Benefits

Purpose

• The purpose of the project is to construct a viaduct to replace damaged but temporarily stabilized retaining wall under an emergency contract.

Need

• 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.
