Central Waterfront

• Earlier this week, crews rerouted six blocks of waterfront traffic from Alaskan Way to a newly improved road beneath the viaduct. The traffic switch – which will last through at least early 2014 – changes the way drivers, bicyclists and pedestrians travel along the waterfront south of Spring Street. It also affects ferry access and parking. Visit our website for more details.
