SF protesters briefly block Van Ness Ave. in opposition to Dakota Access Pipeline

SAN FRANCISCO (BCN) A small group of protesters briefly blocked a major San Francisco thoroughfare this morning in opposition to the Dakota Access Pipeline project.

Around 9 a.m., the group blocked traffic at Market Street and Van Ness Avenue, according to police.

Protesters had also gathered outside a nearby building located at 1455 Market St., where the U.S. Army Corps of Engineers has an office.

The building also houses Uber's headquarters.

The Army Corps of Engineers authorized the nearly 1,200-mile long pipeline project, which would run through areas of North and South Dakota.

Standing Rock Sioux tribe members have said the area is considered tribal lands. Opponents also believe the pipeline would pollute waterways used by tribe members.

While traffic was briefly blocked at the intersection, the protest remained peaceful and no one was arrested, according to police.

San Francisco Municipal Railway service was not affected and the protest was cleared by about 9:30 a.m., according to Muni spokesman Paul Rose.
