Here’s what you need to know about commuting during the Black Lives Matter protest

Sacramento police closed busy intersections Tuesday afternoon as a Black Lives Matter protest marched through the streets of downtown near the Convention Center, where a statewide law enforcement conference is taking place.

Demonstrators appeared to begin dispersing around 4:15 p.m. and had cleared out by 4:45 p.m. Their protest began at 11 a.m., periodically closing different intersections in the downtown area.

Commuters may consider avoiding the I and J street corridors, both of which protesters shut down at various points Tuesday. Sacramento Regional Transit has already announced a detour on Route 30 that avoids J Street between 10th and 15th streets.

At 2:30 p.m., about 75 people changed and marched through the streets. Police on motorcycles rode ahead of the protesters and diverted traffic as a helicopter hovered overhead. Police at one point blocked a ramp onto Interstate 5 at I Street as protesters gathered in front of them.

At 3:30 p.m., protesters blocked the J and 13th Street intersection. They put fake caskets in the road in spite of police warnings to disperse. J Street was closed to traffic at the 12th Street intersection.

By 3:45 p.m., protesters had moved onto I Street, blocking traffic in front of the Department of Justice building. Police shut down I Street from 13th Street to 14th Street in response.

The protest started outside the Sacramento Convention Center, where police were gathered for an all-day conference. The protests, which came on the six-month anniversary of the police killing of Stephon Clark, focused on police violence against African Americans.
