AlaskanWay

MENG Analysis worked on the Alaskan Way Viaduct and Seawall Replacement project by considering a $4 billion tunnel alternative. The alternative would remove the Alaskan Way Viaduct structure and replace it with a six-lane single-level tunnel located between the existing viaduct and the seawall. This was a complex technical challenge in its own right. Even more challenging are the urban planning, environmental and construction impacts resulting from a project of this scope and complexity. The study offered a number of substantial alternatives to the technical design that can result in considerable cost and schedule savings while still maintaining project quality. This is a multifaceted project with many tradeoffs, and various options are still being considered.
