A fire burned a vacant building on a plot of land owned by the California High Speed Rail Authority.
Black smoke could be seen for miles — especially around highways 99 and 41 — when the fire started around 1 p.m.
Several units from the Fresno city and county fire departments responded, with the CHP stopping traffic on Cedar.
The Fresno fire department said the fire erupted in a vacant commercial structure. There were no reports of any injury, or details on how the fire started.
