Restoring Seattle's Historic Aurora Bridge

摘要

The George Washington Memorial Bridge-or the Aurora Bridge, as it's more commonly known-is a 2,945-ft (897.6-m) long, 70-ft (21.3-m) wide cantilever and truss structure that spans Lake Union and connects the Queen Anne and Fremont neighborhoods in Seattle, Washington, USA. Opened to traffic on February 22,1932, the Aurora Bridge was the first major highway bridge built in Seattle and was later listed on the National Register of Historic Places. But as one might expect from a structure nearly nine decades old, the bridge had seen better days. In fact, it exhibited "a combination of chalked and weathered paint, as well as pack rust and pinpoint rust in certain areas," says Nick Capuzello, corporate health and safety officer for Liberty Maintenance, Inc. Factoring in areas that needed steel repair, including the replacement of ～3,000 rivets, Capuzello concludes that the bridge "should've been recoated several years ago."
