New Cesar Chavez Boulevard Underpass Reconnects Downtown, Southwest Fresno

Cesar Chavez Boulevard is open again beneath the future high-speed rail corridor, ending a four-year construction closure that severed a key route linking Southwest Fresno, Chinatown, and the southern edge of downtown. The California High-Speed Rail Authority reopened the underpass on Tuesday, March 10, completing a 1,000-foot, 90-foot-wide grade separation between F and H Streets that drops traffic more than 15 feet below the Union Pacific Railroad tracks and the future high-speed rail alignment.

The structure, the 59th grade separation completed under the statewide high-speed rail program and the first finished in 2026, carries two lanes of vehicle traffic alongside bike lanes and protected walkways. Work began in summer 2021, and the corridor remained closed throughout the construction period.

The reopening follows a similar milestone on Tulare Street, which had been closed since 2017 before reopening as a high-speed rail underpass last summer. Together, the two underpasses represent the most significant restoration of cross-rail connectivity in central Fresno since the authority's construction program accelerated through downtown.

The relief was not expected to last long for Fresno streets still caught in the construction path. Augie Blancas, a California High-Speed Rail Authority spokesperson, said in an emailed statement that Mono Street will be permanently closed to traffic. Fresno Street, which already passes beneath the existing Union Pacific tracks, will close later this spring when reconstruction begins there. "Fresno Street will remain an underpass but will be reconstructed to allow traffic to travel under the Union Pacific and high-speed rail tracks safely," Blancas said, adding that the project could run through spring or summer 2027.

Grade separations at McKinley Avenue and Shaw Avenue are also underway, with both streets slated to become overpasses above the tracks. The Shaw Avenue work has already pushed multiple detours near its busy intersection with Golden State Boulevard. The Fresno Bee reported the authority is aiming to finish the McKinley and Shaw overpasses this fall or winter.

The authority has framed the broader separation program as a safety imperative: removing points where roadway traffic and rail lines cross at grade eliminates conflicts that slow trains and create hazards for drivers and pedestrians alike.

Community reaction to the Cesar Chavez reopening was broadly positive, with social media comments citing relief over restored connectivity and shorter commute routes through the corridor. The authority noted the structure is designed with bike lanes and protected walkways, though confirmation that those facilities are fully open to the public at reopening was not immediately available.
