Seattle Opens Longest Road Tunnel in the U.S.

SEATTLE’S HIGHWAY 99 tunnel, the longest road tunnel in the contiguous U.S., opened Monday, offering the public easy access from the city’s downtown to its waterfront attractions.

The $3.3 billion, 2-mile-long tunnel will replace the earthquake-damaged Alaskan Way Viaduct, which the city plans to tear down this month to make way for a new and improved waterfront area and eight acres of new public parks, according to The Washington Post.

With an updated waterfront, and better access to that area’s popular attractions including the Seattle Aquarium, officials hope the tunnel will boost Seattle’s tourism industry and bring the city’s infrastructure into the 21st century.
