Lake Washington Bridge / Homer Hadley Bridge
Posted February 15, 2011, by K. A. Erickson

This is the Westbound portion of I-90 across Lake Washington. It was completed after three years of building. It is recognized as having historic qualities. Y'all can add Bing, Google, Alta Vista views and street images to hearts content.
