Golden Gate Bridge District board just voted to approve one-time closure of NB lanes on bridge from 6-9am on Sunday 7/23 for SF marathon— Kate Larsen (@KateABC7) June 23, 2017
The idea follows recent attacks by people who drove vehicles into large crowds of people.
During previous races, the bridge left one northbound lane open and allowed traffic on southbound lanes.
"In the past, northbound traffic has been allowed to proceed with traffic cones," said Priya Clemens, spokesperson for the Golden Gate Bridge District. "And considering world events, we don't think that's the safest way to go about this activity."
Under the plan, the lanes will be closed from 6 to 9 a.m. Sunday, July 23.
