Sea-Tac Airport To Close Center Runway For 60 Days For Refurbishing

The Port of Seattle announced that the center runway of Seattle-Tac Airport will be closed for concrete panel replacement for 60 days this summer, beginning Monday, July 12 through Friday, Sept. 10th.

According to the Port of Seattle, the project is intended to replace deteriorating concrete surface panels on runway 16C/34C, in order to allow for continued safe operation of the runway until full reconstruction, which is slated in 2016. Approximately 150 panels will be replaced to address degradation such as cracking, spalling, and faulting which can result in concrete debris that can break loose and be hazardous to aircraft. This number represents less than four percent of the approximately 4,000 concrete panels that make up the center runway.

Runway 16C/34C was originally constructed in 1969, with a 20-year design life. The Port began a Runway Improvement Program in 1993 to rehabilitate and extend the useful life of the runway. More than 400 concrete panels have been replaced since the beginning of the program.

The Port claims that the cost of the project is anticipated to be completed at “less than the projected budget of $5.65 million due to lower construction bids,” according to a statement.

All air traffic will be directed to the outer two runways during the project, which means a likely increase in use of the third runway. Construction work will be done during daytime hours to reduce noise impacts to area neighborhoods during the evening.

During the closure, airport neighbors may notice increased noise associated with changes in runway use. Most departures are expected to be on the runway closest to the terminal and most arrivals on the third runway.

Finish work, such as striping and pavement sawing, is scheduled to occur during overnight hours up to two weeks after the runway reopens. This low impact finish work will not require daytime closure of the runway.

The runway closure will not affect airline flight schedules or passengers.

    With all the noise coming from the use of the third runway,
    I thought the second runway was already closed.
