The scheme is being advanced following the completion of a feasibility study in 2024 and aims to improve resilience, safety and mobility along a critical north-south corridor between Pine Avenue and State Route 71.
The scheme is located in the Prado Basin, an area not formally designated as protected but one containing sensitive wetlands and habitat managed by the US Army Corps of Engineers as part of the Prado Dam flood-control system.
The project proposes replacing the existing Chino Creek Bridge with a new Euclid Avenue Viaduct around 732m in length, carrying a widened four-lane roadway together with dedicated pedestrian and bicycle facilities. The elevated structure will lift the corridor clear of the 50-year flood inundation zone to reduce future storm-related closures and improve access for motorists and pedestrians during heavy rainfall.
Environmental review now underway will assess hydrology, flood behaviour, biological resources, site topography, and construction-stage impacts.
The City is accepting public comments from today (12 January) through to 10 February 2026.
Following completion of the environmental process, the city of Chino anticipates advancing into engineering and final design in autumn 2026, with construction targeted for summer 2027.
