SACRAMENTO-

A crowd protesting a grand jury decision to not indict Ferguson Police Officer Darren Wilson tried to block a Highway 99 on-ramp at Florin Road Monday night.

Sacramento County Sheriff's deputies and California Highway Patrol officers are trying to keep the roadways clear but there is still a traffic backup.

Protesters generally kept to the street corner near the on-ramp.

The situation was tense but mostly peaceful through the evening.

Demonstrators in Ferguson, Mo. completely blocked a portion of Interstate 44.
