Police and King County Metro Transit are bracing for a potentially large-scale protest, which could snarl traffic around Seattle.

King County Metro transit is warning riders that an Occupy Seattle protest on eduction this afternoon could disrupt bus service around the University of Washington, and possibly the rest of the city.

A statement from Metro warns that "Due to the time and location and other variables, this event could cause widespread traffic delays over a much larger area, as well as delays to transit service beyond the U District."

Occupy Seattle protesters began marching from Seattle Central Community College—where Occupy Seattle's main camp is located—down to Husky Stadium around 3:30 pm. Police tweeted that at least 150 people were involved in the protest.

A post on the Occupy Seattle's Facebook page says the march was to "defend against the attacks on public education coming from Olympia and Washington, DC." The group also tweeted there would be "direct action...on University Bridge. Not Montlake."

However, police tell PubliCola they're concerned the group could try to block both the University and Montlake bridges.

Last month, of course, the Occupy protests in New York heated up when protesters clashed with police on the Brooklyn Bridge.
