Occupy Wall Street organizers plan hundreds of marches, strikes and teach-ins in 120 cities around the country on Tuesday for what they call a “general strike” for economic justice.

May Day protesters from New York labor unions, immigrants groups and others are expected to march from Union Square to Wall Street on Tuesday for “A Day without the 99 Percent.”

New York Mayor Michael Bloomberg has said that law enforcement is ready to manage what is expected to be a day of wide-ranging demonstrations throughout the city, including possible bridge and tunnel blockades, dozens of smaller pickets and a “pop-up” occupation of Bryant Park across the street from the headquarters of Bank of America. Officials in other cities, such as Seattle, have warned of the possibility of vandalism and violence.

Other big actions are planned for the West Coast, including a large march in the San Francisco Bay area. Organizers said a plan to shut down the Golden Gate Bridge has been scrapped.

Locally, members of Occupy D.C. plan a festival and rally at Meridian Hill Park beginning at 3:30 p.m., followed by a 6:30 march from the park to the White House. Marchers plan to head down 14th Street to New York Avenue to the White House. A D.C. police spokesman said they have no plans to shut down lanes of traffic to accommodate them.

Occupiers have called Tuesday their “coming out party” and the start of their spring resurgence, after the cold weather lull that followed the eviction of dozens of Occupy camps across the country in the late fall and winter.
