Southbound I-5 and I-805 have reopened to traffic at the San Ysidro port of entry after being closed for several hours, Caltrans says.
Sunday afternoon, authorities closed Southbound Interstate 5 and I-805 at the U.S.-Mexico border.
Traffic was diverted to State Route 905 during the closure.
Across the border, protesters continue to voice their objections to a sudden hike in gas prices in Mexico: 20 percent in one day.
Last weekend, the San Ysidro port of entry closed briefly in the southbound direction due to protesters blocking the lanes.
No further details were available.
