A bomb squad detonated a suspicious device along the eastbound Cap City Freeway in Sacramento early Monday evening.
The California Highway Patrol described the item as a cylinder and similar to a pipe bomb. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives were investigating.
A Caltrans worker saw the unknown device along a freeway frontage road and reported it to authorities. The CHP closed the Arden Way exit and the eastbound lanes of the freeway in the area while it investigated. Around 3:30 p.m., traffic was directed to exit at Exposition Boulevard.
All lanes of the freeway reopened to backed-up traffic at approximately 6 p.m.
According to Graham Barlowe with the Bureau of Alcohol, Tobacco, Firearms and Explosives, the incident is an open investigation. Materials found at the scene were sent to an explosives lab in the Bay Area for analysis.
