The southbound lanes at the San Ysidro port of entry have reopened after shutting down for several hours due to protests along the U.S.-Mexico border Sunday.
This is the fourth weekend in a row protests have caused a traffic diversion at the border.
Southbound Interstate 5 and SB I-805 were closed at State Route 905, Caltrans officials said. Lanes reopened around 5 p.m.
Northbound traffic was not affected by the protest, according to the CHP.
Those looking to cross into Mexico had to go to the Otay Mesa Port of Entry.
In Tijuana, Mexico, protesters continue to voice their objections to a sudden hike in gas prices in Mexico: 20 percent in one day.
