Why Do The Waves Only Churn On The South Side Of 520?


By By Steve Pool

SEATTLE - Laura wanted to know why it seems that every time she's driving on the 520/Evergree Point Floating Bridge, that the water seems to be choppy on the south side of the bridge, but calm on the north side.

It's mainly because a majority of the time we have gusty winds, they come from the south. The barrier the bridge forms also helps to churn up the water somewhat on the windy side. In the meantime, the bridge blocks the wind along the north side, leaving it eerily calm.

However, there are times when we have a strong arctic wind event that it can be reversed, and the choppy water is on the north side.

The DOT says they would open the 520 bridge's drawspan if sustained winds reach 50 mph for 15 minutes.

Each year since 1998 our family has a tradition of putting up a scarecrow in our front yard during the month of October. We decide as a family what character we are going to do and it's a family secret until he goes up. Most of the time we create the entire outfit from scratch.
