A group of people who say they are Stanford students blocked westbound traffic on the San Mateo Bridge beginning just before 5 p.m.

Citing television footage, the Chronicle says police officers have made arrests after the students, some carrying banners and a Palestinian flag, made their stand. Protesters reportedly said they hoped to shut traffic down for 28 minutes, which it sounds like they didn't do. There were several minor accidents as cars came to a halt.

68 were arrested, with the CHP issuing the following statement: “The CHP would like to remind the public that our freeway system is no place for protests. Motorists do not expect pedestrians to be present in lanes of traffic, and such actions could lead to collisions between those pedestrians and the vehicles on the freeway. Unfortunately, collisions involving pedestrians often end with major injuries or fatalities. We thank those that were affected by this incident for their patience and cooperation.”
