Alaskan Way Viaduct

The Alaskan Way Viaduct was a elevated highway in Seattle, Washington, constructed in the 1950s. It ran along the waterfront, connecting the central business district to other parts of the city. The structure faced issues like aging, safety concerns, and seismic risks, leading to its closure in 2019. It was replaced by the SR 99 tunnel, a new underground roadway designed to improve traffic flow and safety. The removal of the viaduct opened up waterfront areas for development and public use, enhancing the city's urban landscape.
