On Tuesday, Aug. 18th, the Port of Seattle hosted members of the press at a tour of the reconstruction project that is in the final stages of completion on the first (as well as oldest and longest) runway, also known as “16L/34R.”
Approximately 80% of the concrete has already been poured for the new runway, and finishing touches will be completed over the next month. The original concrete runway, built in 1944, is being crushed and recycled as the gravel sub-base for the new runway. This sub base is 12 inches, topped by a 4-inch asphalt layer and then the 20-inch concrete runway.
In comparison, Sea-Tac’s third runway is only 17-inches thick.
This re-construction is the main reason why the airport’s third runway has been in use so much recently.
