According to a statement issued by CHP spokesman Officer Sean Wilkenfeld, the CHP began to receive numerous 911 calls at 12:45 p.m. that a big rig was on fire on I-80 westbound near Gilman Street in Berkeley.

CHP Oakland officers, as well as firefighters from Berkeley and Albany, were dispatched to the scene and confirmed that the trailer was on fire. A Sig alert has been issued and the fire has been contained. Firefighters are on scene to monitor the situation.

As of 1:50 p.m., three lanes of the freeway were closed on westbound I-80 at Gilman. The Gilman Street off-ramp was also closed for a time because firefighters are using a water source off the freeway and have hoses across the ramp.

As of 2:10 p.m., the CHP had re-opened the off-ramp and one lane of traffic, leaving the two right-most lanes closed.
