Fire at Church Avenue High-Speed Rail Overpass Halts Work, Trains

Temporary plywood-and-lumber falsework used to form the Church Avenue overpass for the California High-Speed Rail project burned shortly before 9 a.m. Wednesday, forcing an evacuation of workers, halting construction and temporarily stopping train traffic in southeast Fresno.

About 20 construction workers on site at roughly 8:45 a.m. evacuated immediately, the Fresno Bee reported. Fresno Fire Department spokesperson Josh Sellers said firefighters found "a lot of plywood and lumber" fueling the blaze and that crews attacked the fire from above using ladder trucks. Sellers described the burned materials as "the shoring framework that the concrete is then poured in place, and that becomes the permanent structure."

Fresno Fire deployed roughly 20 firefighters to the scene, according to multiple reports. Positioning a ladder truck over the work zone required coordination with railroad officials and the temporary closure of tracks. "We have the railroad tracks here that we ended up having to close down and stop the trains because we have a ladder truck in place that's blocking the tracks," Sellers said. Officials reported the fire was under control by late morning, though hot spots continued to smolder.

The California High-Speed Rail Authority issued a brief statement thanking Fresno Fire: "Thanks to the work of (the) Fresno Fire Department, the fire has been extinguished. We will continue to support and coordinate as needed." Investigators say the blaze was likely ignited by routine construction activities; no definitive cause has been announced and no injuries were reported.

Access to the site was complicated early in the response by road closures and heavy fog, the Fresno Bee reported, slowing the arrival and placement of apparatus. Photographs and aerial video referenced by KFSN indicate the burned falsework sits where concrete will be poured to complete the overpass near Church and Sunland avenues.

The Church Avenue overpass had been scheduled for completion in March 2026, according to KFSN and other outlets; HSRA and contractors have not yet said whether the fire will delay that timeline. The incident lands against the backdrop of long-running challenges for the statewide high-speed rail effort, which multiple outlets have described as years behind schedule and facing major cost overruns.

For Fresno County residents, the immediate impact was limited: workers evacuated safely, no injuries were reported, and train traffic was stopped only briefly while firefighters worked. Longer-term implications hinge on damage assessments and contractor and HSRA statements still pending. Local officials and the rail authority are the next stops for details on structural damage, repair timelines and whether the March 2026 completion target remains realistic.
