the first target was northbound 880 at fifth avenue in oakland, just after 6 a.m. protesters chained themselves to 55 gallon drums filled with cement. the chp had to jackhammer those apart and didn't get all lanes open until 1 p.m. it took about four hours to open the golden gate bridge. here's the moment that those cars finally got moving. protesters used chains and pipes to secure themselves to cars that they had parked across all three southbound lanes, attempting to block or shut down a freeway or a state highway to protest is unlawful. >> it's dangerous, and it prevents motorists from safely reaching their destinations, the chp says it got all lanes of southbound 880, reopened at 1 p.m, but some drivers crossed the median to get out of the gridlock. >> 300 people walked up the seventh street on ramp onto the freeway around 8 a.m. and happening now. another protest, this time
