OLYMPIA, Wash. - Seattle Mayor Greg Nickels says the Alaska Way Viaduct in Seattle will be replaced with a tunnel.
Nickels told The Seattle Times that the governor, city, county and port have reached an agreement for replacing the aging roadway that was damaged in a 2001 earthquake.
Officials have scheduled a Tuesday morning news conference to share their plans.
State transportation officials had recommended either another elevated highway or improved surface streets. But other interested parties, including the mayor and the Seattle Chamber of Commerce, favor a tunnel.
The tunnel is the most-expensive option at more than $4 billion. The elevated and surface plans would cost more than $3 billion. The state has committed $2.8 billion for the project.
