Last week, I had the opportunity to get a behind-the-scenes look at the construction currently in progress on Runway 16C/34C at Seattle-Tacoma International Airport (SEA, aka Sea-Tac). The center runway closed on May 4th for a complete reconstruction and is scheduled to re-open October 30th, so the project is already well underway.
At 9,426 feet in length, 16C/34C is Sea-Tac’s second-longest runway, consisting of over 4,000 concrete panels, each measuring 20 feet x 18.75 feet. Needless to say, reconstructing a runway is a huge undertaking, so there was plenty to see on our tour!
Originally built in 1969, 16C/34C is the oldest runway at Sea-Tac. It was designed to last 20 years, so it has more than done its duty. Upon completion of this reconstruction project, all three of Sea-Tac’s runways will have been constructed or rebuilt within the last seven years. 16R/34L (the hotly-contested “third runway”) was built in 2008, and the longest runway, 16L/34R, was reconstructed in 2009.
“We continue to grow at a tremendous rate and the reconstruction of Sec-Tac’s center runway is vital to serve the demands of our region with progressive steps to improve safety, efficiency and environmental stewardship”, said Mike Ehl, Director, Aviation Operations. “This will bring all of our runways up to modern standards for reliable use for decades to come.”
