Seattle Freeway Replacement Plans Whittled to Two Options
"Transportation planners from the state, King County and the city of Seattle presented the governor and other elected officials with two options:
• A "surface and transit" plan that features three southbound lanes on Alaskan Way and three northbound lanes on Western Avenue.
• An elevated bypass highway that has two lanes in each direction, running side by side on independent bridge structures - the cheapest of the highway scenarios, the state says. It would include a Western Avenue exit to Belltown, Seattle Center and Interbay."
"The surface-transit option is estimated to cost $3.3 billion, and the elevated version $3.5 billion. That's higher than earlier estimates because improvements to Interstate 5, local streets and transit have been added."
