The City of Chino has launched environmental review for the Euclid Avenue Bridge Project, an effort to modernize one of the region's most critical—and problematic—north-south corridors.

Euclid Avenue links the 60 and 71 freeways, supporting commuter traffic and goods movement across four counties. But the aging two-lane bridge over Chino Creek has long struggled with congestion, safety concerns, and storm flooding that can shut down the corridor entirely.

Proposed improvements would elevate the bridge above flood levels, widen Euclid from two to four lanes, and add bike and pedestrian facilities. The city also plans to repurpose the existing bridge as a wildlife crossing at Chino Creek.

Design funding comes from Measure V; construction depends on state and federal grants.

The Euclid Bridge is one piece of a larger corridor improvement plan that includes the $140M Pine Avenue extension to the 71 Freeway and interchange improvements.

That plan hasn't been without controversy. In December 2024, Chino Hills withdrew its $4.2 million commitment to the Pine extension after costs tripled from original estimates. Councilman Art Bennett said he'd "rather retain this money for projects that would benefit our residents than throw it into a big hole." Chino Mayor Eunice Ulloa pushed back, noting one-third of the extension runs through Chino Hills. The city's Public Works Director emphasized it would serve as a wildfire evacuation route for Chino Hills.

Public scoping runs through February 11, 2026. Two meetings scheduled:
