The Eastside portion of the 520 project will reach a major milestone this summer – it’ll be mostly done by August/September. There will be punchlist work for some of the fall, but major disruptions should end. I know it’s been a bear of a project.
Over the next few weeks you’ll see some major changes in traffic flow. I am sure it will be seriously aggravating. Closing the entire corridor for a year would have been worse. Letting it sink in a storm worse still.
The attached email from the 520 project people details what you should expect over the next few weeks. It’ll be closed every weekend except June 16-18 to allow for the UW graduation.
