Video shows extent of SR 520 construction

Friday, July 19, 2013by  Jon Osterberg

Commuters frustrated by weekend SR 520 bridge closures can be assured: those disruptions are warranted. There’s plenty of work going on.
   Want proof? Just check out the WSDOT video.
   As a daily 520 commuter, I’ve driven into Seattle from the Eastside after weekend closures and sometimes been unable to discern progress. It hadn’t occurred to me that significant construction might be going on underneath the roadway.
   During the July 12-15 shutdown, crews excavated the entire freeway east of 108th Avenue N.E. and installed a large fish culvert, while engineers to the west conducted a full inspection of the Evergreen Point Floating Bridge.
   By 5 a.m. Monday, July 15, the freeway reopened to traffic, as did I-405 through downtown Bellevue, which had been closed while crews replaced the left two lanes with 500 new concrete panels. Watch WSDOT’s amazing time-lapse video of the SR 520 work.
