Sea-Tac Airport will open its third runway on Thursday, November 20th, 2008 after 16 years of development and costs more than $1 billion.
Sea-Tac's new third runway is designed to help decrease delays during low visibility conditions, which occur approximately 44% of the year. The third runway will allow two streams of traffic to land in lower visibility conditions. Currently, Sea-Tac's two runways are too close to each other to allow two streams of traffic to arrive in such condition.
