10-1V390-DO Culvert and Sinkhole Repair

The California Department of Transportation, through District 10 in Stockton, is initiating a project to address critical infrastructure failure at post mile 11.38 on State Route 99 in Ceres, Stanislaus County. The work centers on replacing a compromised culvert that has led to the formation of two sinkholes on the northbound onramp, threatening the structural integrity of the roadway. The scope encompasses full excavation, removal of the damaged culvert, installation of a new drainage system, stabilization of the sinkholes, and restoration of the pavement surface. This effort is essential to prevent potential loss of life, damage to property, or disruption of essential public services by ensuring the long-term stability and functionality of the transportation corridor. The project is officially designated as 10-1V390-DO Culvert and Sinkhole Repair and has been posted as a forecast with a public notice date of June 5, 2026. While no solicitation number or set-aside details are currently available, the work is being managed by Caltrans and coordinated through the agency’s environmental planning team. Primary point of contact for inquiries is Ishnav Guleria, Associate Environmental Planner (Generalist), who can be reached via phone or email. The project site is located in Ceres, California, and all work will be conducted in accordance with state transportation and environmental standards to mitigate risks and restore safe, reliable highway operations.
