Northbound Interstate 280 reopened Thursday night after the San Mateo County Sheriff's bomb squad was called out to investigate a suspicious backpack fire that stopped traffic for an hour, according to the California Highway Patrol.
The fire was first reported around 6:43 p.m. on northbound I-280 near Edgewood Road.
After the fire was extinguished, the backpack needed to be X-rayed to ensure that it could be safely removed from the roadway, according to the CHP.
A Sig-alert was issued at 7:04 p.m. for all northbound lanes of the roadway.
At 8:08 p.m. the CHP reported via social media that no threat to the public had been found in the backpack and all lanes of the roadway had reopened.
