Wall St. protest shuts half of B'klyn Bridge

The Brooklyn Bridge has been shut down in one direction after protesters camped out near Wall Street spilled onto the roadway.

Police have made dozens of arrests and were continuing to stop people illegally blocking the roadway Saturday evening.

Demonstrators are railing against corporate greed, global warming and social inequality, among other grievances.

The group has been camped near the Financial District for two weeks and clashed with police on earlier occasions. A Friday march to police headquarters was peaceful.

Earlier Saturday, two other marches went over the bridge without problems. One was from Brooklyn to Manhattan by a group opposed to genetically modified food. Another in the opposite direction marched against poverty.
