 Northbound lanes of I-5 are going to be narrowed to just two lanes all weekend. The lane closures are between Boeing Access Road and Georgetown. They're going to start at 10 o'clock tonight and continue through early Monday. It also happens to be a weekend full of activities around the Seattle area, including plenty of music at the Capitol Hill Block Party, the Bye to Seattle, Seattle Sounders, and Seattle Rain, and the Mariners.
