San Mateo County Bridge Repair Project (EA 3Y620)

Caltrans plans to repair bridges along SR-380 and US-101 at the El Camino Real Avenue Undercrossing and the SR-380/US-101 separation in San Mateo County, with construction scheduled to begin in July 2026 and conclude by October 2026. The work includes removing unsound concrete, patching deck spalls, replacing joint seals, repairing slope paving and asphalt concrete approaches, backfilling erosion gulleys, applying a polyester concrete deck overlay, painting bridge identification markers, and fixing large spalls on concrete curtain walls. All activities will be conducted strictly within Caltrans right-of-way, with equipment staged on bridge decks or freeway areas to minimize disruption. The project is designed to halt further deterioration and extend the structural service life of the bridges and roadway approaches. The project has been determined eligible for a categorical exemption under the California Environmental Quality Act (CEQA), specifically Class 1(d) under PRC 21084 and 14 CCR 15301, which applies to maintenance and repair of existing facilities. The contract is currently listed as a forecast with no solicitation number, estimated value, or formal award details, indicating it is a planned initiative rather than a recently awarded agreement. The project site is defined by specific post mile markers on US-101 and SR-380, covering areas in South San Francisco and San Bruno. The designated office for environmental coordination is Caltrans District 4 in Oakland, with Juliane Smith, Senior Environmental Scientist, serving as the primary point of contact for NEPA and CEQA compliance. No federal acquisition regulation clauses, contract-type specifications, pricing data, payment instructions, or offeror certifications are included in the available documentation, as the materials primarily support environmental compliance and project scoping rather than procurement details. There is no indication of competitive bidding, evaluation factors, or subcontracting requirements in the provided information.
