ST. GEORGE, Utah — A southern Utah airport serving more than 200,000 commercial passengers a year will close for four months to let crews rip up and rebuild a runway undermined by unstable blue clay. St. George Regional Airport manager Rich Stehmeier tells The Spectrum the closure is scheduled May 29 to Sept. 26. Plans call for digging 17 feet beneath the more than 1-mile (1.6 kilometre) long runway and installing more stable material. St. George is about 120 miles (193 kilometres) from Las Vegas and 275 miles (443 kilometres) from Salt Lake City. The airport handles Delta, United and American flights to Phoenix, Denver, Los Angeles and Salt Lake City.
