Ever wonder what’s going on with all the construction activity at SEA? From the north side to the south end, and even underground, you’ll find updates and improvements designed to make your travel experience easier and help you discover something new. Your adventure begins at SEA: Modern new facilities, 135 retail and dining options, accessibility upgrades, faster and easier ways to get around. We’re meeting the diverse needs of our travelers while promoting air and water quality, renewable and sustainable fuels, noise reduction, and wildlife protection. That’s exciting – because construction at SEA is good for the local economy. It’s good for local jobs. And, of course, it improves your travel experience. We’re bringing you modern services, extra elbow room, and sustainably designed spaces, and leaving you more time for yourself. We want passengers to spend their time discovering a new restaurant or enjoying our public art, not waiting in a traffic jam or a security line. We’re also working on projects that improve operational efficiencies in our existing terminal and concourses to help keep you moving. Looking beyond today, Near-Term Projects included in our Sustainable Airport Master Plan propose to add a second terminal, 19 new gates, and more ways to meet regional demand for the next decade. We are collaborating with regional partners on our long-term vision as we prepare to serve demand for decades to come, all while prioritizing environmental and financial stewardship.
