Title: Economic Importance of Seattle’s Alaskan Way Highway Tunnel
Accession Number: 01748051
Record Type: Component
Record URL: Availability: Find a library where document is available Abstract: In 2009, earthquake damage led Washington State officials to replace the Alaskan Highway Viaduct—then nearly 50 years old—with a bored tunnel. Completed in 2019, the 1.756-mile Alaskan Way Viaduct replacement tunnel is the largest earth pressure balance bored tunnel in diameter in the world. The tunnel is designed to withstand a 2,500-year earthquake and features smart transit technology, including more than 300 cameras that monitor traffic, safety conditions, and security. This article tracks the project’s beginnings, process, and future as a key component to the redesign of Seattle’s central waterfront.
