Bike lane is nice, but here comes a ship.  Notice sign says "gap in bridge."  Gates swing closed.  Center section starts turning.  This is a rare kind of draw bridge.  Instead of sections raising up, roadway pivots to the side.  Lets ships pass and then turns back into place.  Due to precise balancing and bearing systems, they say it only needs a 1 horsepower electric motor to turn.  It moves slowly, but surely.  Amazing what they can do.  Upper bridge is West Seattle Freeway, while lower one takes local car traffic, pedestrians and bikes.  Scroll down to see bridge as it opens.
