Content: I-5 continues as British Columbia Highway 99 at the U.S.- Canada border's Peace Arch crossing, between Blaine and Surrey. State Route 99 is also a major arterial in the western half of the city; it included the now-defunct Alaskan Way Viaduct along the Seattle waterfront. The Alaskan Way Viaduct replacement tunnel was opened in place of the elevated viaduct in February 2019 on account of seismic instability. Transportation to and from the east is via State Route 520's Evergreen Point Floating Bridge and Interstate 90 's Lacey V. Murrow Memorial Bridge and Third Lake Washington Bridge, all over Lake Washington. Those bridges are respectively the first, second, and fifth longest floating bridges in the world. State Route 522 connects Seattle to its northeastern suburbs. Two public transportation agencies serve Seattle: King County Metro, which operates local and commuter buses within King County, and Sound Transit, which operates commuter rail, light rail, and regional express buses within the greater Puget Sound region. In recent years, as Seattle's population and employment have surged, transit has played an increasingly important role in transportation within the metro area.
