The march started with a rally shortly after noon on the south end of the Golden Gate Bridge.
About 300 pro-Tibet activists gathered to voice their anger over what they call 'Chinese government repression which they say has gotten worse in recent months.
The demonstrators, escorted by the CHP, marched slowly across the Golden Gate Bridge.
The demonstration was organized by San Francisco Team Tibet, a coalition of pro-Tibetan human rights groups.
Giovanni Vassalo was one of the organizers.
"We're here to voice our solidarity with the people of Tibet who can't voice their feelings freely," said Vassalo.
The march was peaceful with no suprises, unlike the time in April when protestors climbed up on bridge cables and unfurled a large banner.
Today, the demonstrators made their way across the span to Vista Point on the Marin County side.
