AI Contract Overview

Caltrans is preparing to repair a significant rockslide on southbound US-101 near post mile 0.4, just south of Waldo Tunnel, where a storm triggered the movement of approximately 2,000 cubic yards of rock and debris, overtopping the k-rail and obstructing the travel lane. The slide spans 40 feet in width and 200 feet in length, leaving the slope unstable with loose and overhanging rocks posing an ongoing risk. Initial response by field crews cleared debris and restored access, but inspections revealed extensive damage including about 220 feet of compromised k-rail and a 4-foot-high fence mounted on the barrier. The project requires the removal of all loose and hazardous rock material from the slope and behind the barrier, followed by grading to restore structural stability and proper alignment. All damaged infrastructure—including the fence, k-rail, and any compromised drainage systems—will be repaired or replaced to ensure full functionality and safety. Temporary traffic control measures will be in place throughout construction to protect workers and motorists during the work.

Full Description

Show more
Caltrans proposes repairing a rockslide that occurred on southbound US-101, just south of Waldo Tunnel, at post mile (PM) 0.4. The rockslide occurred as a result of a storm and released an estimated 2,000 cubic yards of rock and debris, overtopping the existing k-rail and entering the traveled way. The slide is approximately 40 feet wide and 200 feet long. Field Maintenance crews responded the same day as the incident by clearing debris and restoring roadway access. Inspections after the incident identified approximately 220 feet of damaged k-rail as well as a damaged 4-foot-high fence that was mounted on the barrier. The slope remains unstable, with loose and overhanding rocks at risk of falling. This condition necessitates immediate slope repair to uphold the integrity and usage of the State Highway System. Construction will involve removing loose material and overhanging rock on the slope and rocks and boulders behind the k-rail. The slope will be graded to restore stability and grade. The damaged 4-foot-high fence that is mounted on top of the barrier will be replaced and the damaged k-rail will be repaired or replaced. Any damaged or impeded drainage will be reestablished. Temporary traffic control will be implemented during construction.
