UPDATED: Protesters Blocking Traffic on I-5 in La Jolla Walk Off

Updated at 12:36 p.m. Nov. 26:

Several dozen protesters lined up across a stretch of Interstate 5 in La Jolla during the morning rush-hour period today, causing a miles-long backup.

The protest on northbound I-5 near Nobel Drive began about 6:50 a.m., prompting authorities to temporarily close lanes. It ended peacefully around 7:20 a.m., after officers ordered demonstrators off the freeway, according to the California Highway Patrol.

Protesters, led by an unidentified man with a bullhorn, held signs objecting to a Missouri grand jury’s decision not to indict Officer Darren Wilson in the Aug. 9 shooting death of 18-year-old Michael Brown, who was unarmed but allegedly came at the officer and, at one point, tried to take his service weapon.

Before authorities arrived on the freeway, several stranded motorists got out of their vehicles and yelled at the protesters to move. At least one frustrated motorist got into a brief physical confrontation with the man holding the bullhorn.

The protesters walked off the freeway and continued their march on city streets under the watch of San Diego police.

Thousands of San Diego drivers delayed Wednesday by protesters who stopped traffic on northbound I-5 in La Jolla. One woman told NBC 7 the protest was connected to the recent grand jury decision in Ferguson, MO.
