SEATAC – Congestion at Sea-Tac Airport may ease soon due to a new high-tech parking system put in place recently.

The new system monitors traffic conditions through cameras and uses signs to help visitors find open parking spaces.

And it’s just in time, as over 109,000 passengers are expected to go through the airport today, the busiest day of the Memorial Day holiday weekend.

Previously, many passengers got stuck in a seemingly endless loop, circling the six floors of the parking garage looking for a place to park.

This new system utilizes 88 cameras to monitor traffic in the garage. These cameras are linked to 80 new signs that direct drivers to floors and rows with available parking spaces.

Once on a floor, a sign will indicate how many spaces are available to the left or right, said the Port of Seattle today. More signs will indicate how many spaces are available within each four-row section.

Friday will be the busiest day of the holiday weekend, but today also has been busy with a projected 105,000 passengers. For the rest of the weekend, Saturday is expected to have 85,000 passengers; Sunday, 75,000 passengers; and Monday, 87,000.

These projected numbers put the weekend in the top third of the airport’s busiest days. The busiest days are during the height of the summer travel season in mid-August.
