Seattle Ship Canal Bridge Closure Periods

To accommodate highway traffic during the three-week period when the Seattle Viaduct closes and before the replacement tunnel opens, three bridge crossings on the Ship Canal will not open to vessel traffic between the hours of 7:00am and 10:00am, and 3:30pm and 7:00pm seven days a week. The extended closure periods will be in effect from January 11, 2019 to February 9, 2019.  The three bridges affected are Ballard Bridge, Fremont Street Bridge, and the University Street Bridge.
