NEW YORK - Occupy Wall Street protesters have clogged streets and tied up traffic around the country to mark the movement's two-month anniversary and to signal that they aren't ready to quit, despite the breakup of many of their encampments by police.

More than 300 people have been arrested across the nation, most of them in New York. Police arrested dozens of protestors tonight as they attempted to make their way across the Brooklyn Bridge. Police say they arrested demonstrators who were purposely blocking auto traffic on the bridge roadway. The march toward the Brooklyn Bridge began in Manhattan's Foley Square just before 6 p.m. More than 1,000 protesters gathered near the New York Stock Exchange and sat down in several intersections. Helmeted police officers broke up some of the gatherings. Stock exchange operations were not disrupted.

A coalition of unions and progressive groups joined Occupy demonstrators in staging rallies at landmark bridges in severalU.S. cities to protest joblessness. Mostly peaceful demonstrations took place in cities including Los Angeles, Las Vegas, Boston, Washington, D.C. and Portland. Most of the arrests were for blocking streets, officials say.
