Euclid Avenue Bridge Project

The Euclid Avenue Bridge Project in Chino, California, is a major infrastructure initiative aimed at elevating Euclid Avenue and replacing the existing Chino Creek Bridge 54-1248 with a new viaduct structure to raise the roadway above the 50-year inundation level of the Prado Basin, estimated at 543 feet above mean sea level. The project will construct a four-lane viaduct spanning Chino Creek and Pomona Rincon Road, designed to a maximum height of approximately 28 feet above ground level, while also incorporating dedicated bicycle and pedestrian lanes to enhance multimodal mobility. The work includes installing retaining walls and importing fill soils to support the new alignment, with construction scheduled to begin in April 2027 and extend over a 24-month period. The primary objectives are to prevent storm-related closures, mitigate flood risks, improve public safety, and ensure uninterrupted transportation circulation during rainy seasons. The project site covers approximately 24.2 acres along Euclid Avenue between Pine Avenue and State Route 71 in San Bernardino County, with all construction activities occurring within this corridor. The project is governed by California environmental regulations, primarily the California Environmental Quality Act (CEQA), and must comply with the California Endangered Species Act, Clean Air Act, and applicable state and local codes, including the Chino Municipal Code and California Code of Regulations. Compliance measures include implementing mitigation strategies to address potential environmental impacts such as air quality degradation, noise, biological resource disruption, and light pollution, all of which were evaluated in alignment with CEQA thresholds of significance. Contract administration and acceptance authority reside with the City of Chino, acting as the Lead Agency, with oversight involvement from the California Department of Fish and Wildlife, the U.S. Army Corps of Engineers, and other regulatory bodies. The estimated contract value exceeds $12.7 billion, driven largely by fuel cost projections for construction equipment over the two-year build timeline, with detailed pricing provided for gasoline, diesel, and natural gas across 2027 and 2028, including potential option quantities. While the solicitation and contract form do not specify a formal contract type, delivery location, or payment terms, the procurement is handled directly by the City of Chino through its Public Works Department, with the Senior Engineer as the primary point of contact. Packaging and marking must adhere to California state mandates under SB 54 and AB 1201, requiring all materials to be recyclable, compostable,
