San Benito US 101 Pavement Rehabilitation Project

Project Description

This project will improve US 101 in San Benito County from post mile 0.00 (Monterey County line) to post mile 7.55 (Santa Clara County line). The project will rehabilitate pavement and drainage systems, upgrade traffic safety systems, and replace Transportation Management System elements, and improve wildlife connectivity.

Project Benefits

Purpose

The purpose of this project is to:

• Preserve and extend the life of the existing pavement
• Restore drainage systems
• Maintain an efficient transportation system
• Upgrade guardrail and other barrier systems to current standards
• Improve wildlife connectivity within project limits

Need

• The project is needed because the existing pavement condition within the project limits is deteriorating, exhibiting distress and unacceptable ride quality. If left untreated, deterioration will continue and result in increasingly higher maintenance costs in the future. Within the project limits, 28 culverts exhibit corrosion and scouring which has led to damaged inverts, shape loss, joint separation, sedimentation, and undermined backfill. Continued culvert deterioration could lead to roadway and embankment failure. To maintain U.S. Route 101 traffic information that is currently collected, one existing traffic census station near the end of its service life needs replacement and two additional traffic census stations will have their loops repaired. Sections of guardrail and other barriers within the project limits do not meet current standards. Additionally, this section of U.S. Route 101 is a California Department of Fish and Wildlife-identified wildlife movement barrier and Caltrans has identified a priority remediation site within the project limits.

Public Outreach
