SR-18 Pavement and Culvert Replacement Project

The California Department of Transportation (Caltrans), District 8 - San Bernardino/Riverside, is preparing to execute the SR-18 Pavement and Culvert Replacement Project along State Route 18 from Post Mile R17.8 to 31.7, spanning from just east of Route 138/18 separation to View Drive in Big Bear Lake, California. The project encompasses a comprehensive range of roadway improvements including cold planing and asphalt overlay, replacement of 14 culverts, guardrail and end treatment upgrades, installation of centerline rumble strips and recessed pavement markers, vegetation control, guardrail patina staining, asphalt concrete dike replacement, Transportation Management System elements, bicycle signage and obstruction markings, bicycle-friendly grates, drainage feature installation or replacement, embankment repair, sidewalk replacement, and installation of concrete barriers at bridge structures. The work is designed to extend pavement service life and enhance safety and mobility for all users, while strictly adhering to environmental regulations under CEQA and California state law. Construction activities are structured to avoid impacts on sensitive species, including the San Bernardino flying squirrel and American badger, with mandatory pre-construction biological surveys and seasonal work restrictions from June 1 to September 30 to protect nesting periods. Environmental compliance is central to the project’s execution, with specific contractual obligations tied to Standard Special Provisions (SSPs) that govern hazardous material handling, emissions reduction, and biological protection. Contractors must comply with SSPs addressing lead-containing paint and thermoplastic residue, asbestos notification, treated wood waste management, and non-hazardous earth material handling. Emissions reduction mandates require equipment to be properly maintained and certified under CARB regulations. Biological survey requirements, including identification and fencing of rare plant areas, must be completed within one week of construction commencement. While the project has a federal funding allocation of $4,224,000 from the Federal Transportation Improvement Program for FY 2025/26, no explicit contract type, pricing details, payment terms, invoicing procedures, or contracting officer details are provided. Submissions of public comments are due by August 31, 2026, via email or postal mail to the designated Caltrans point of contact, Malisa Lieng. The project is currently in a forecast stage with no formal solicitation number or binding contract documents yet issued, and all contractual obligations are centered on environmental stewardship and Caltrans-specific standards rather than standard federal acquisition clauses or procurement evaluation factors.
