Sea-Tac Airport breaks ground on major expansion project

SEATAC, Wash. - Sea-Tac Airport is breaking ground on a major expansion Friday afternoon.

The multi-million dollar project will add more than 180,000 square feet to the airport's aging North Satellite terminal and double the amount of space dedicated to eating and shopping.

During the expansion, crews will also make seismic upgrades throughout the airport.

Over 20 gates will be available for use after the expansion, airport officials say. Previously, there were 12 gates.

Alaska Airlines will become the sole airline working out of the terminal after the project.

The terminal will also feature improved Wi-Fi.

U.S Sen. Maria Cantwell is expected to join Port of Seattle Commissioner Stephanie Bowman, Alaska Airline officials and local labor representatives for the groundbreaking Friday.

The redesign was approved by port commissioners in September. Sea-Tac officials estimate the project will be completed by 2021.
