Hundreds of face masks spill onto I-880 in Union City

UNION CITY, Calif. (KTVU) - Traffic on southbound Interstate 880 in Union City was brought to a standstill Wednesday afternoon after hundreds of face masks spilled onto the roadway. 

The incident occurred around 1:39 p.m. near the Whipple Road off-ramp. 

According to the California Highway Patrol traffic log, a caller reported that someone threw the face masks from a vehicle, although authorities have not yet confirmed how they ended up on the highway. 

A KTVU viewer told us she was in a Union City OO Liquor store on Whipple Road when a distraught truck driver came in and said the masks had fallen off his truck. 

CHP officers stopped traffic for a short period of time as Caltrans crews picked up the masks.
