The Working Waterfront 

The Port of Seattle is an
international gateway creating
jobs and economic growth for
the region in an environmentally
responsible way. 
We must have a transportation
system that moves people and
cargo quickly and efficiently. 


4

Port of Seattle relies on an 
efficient transportation system 
Our priorities for an Alaskan Way Viaduct Replacement Program (AWVRP): 
provides sufficient capacity to
move freight traffic efficiently 
grants easy access to our
cargo, commercial fishing and
cruise facilities and 
Sea-Tac Airport 
minimizes construction
disruption 

5

Port of Seattle relies on an 
efficient transportation system 
Without the capacity and connections we need, cargo  and
the jobs associated with it  will go away, and the thousands
of businesses dependent on maritime, trade and passenger
activities will be in jeopardy.
