SEATTLE - Thousands of bridges around the U.S. may be one freak accident or mistake away from collapse, even if the spans are deemed structurally sound.

Bridge regulators call the more risky spans "fracture critical," meaning that if a single, vital component of the bridge is compromised, it can crumple.

Fracture critical bridges, like the I-5 span in Washington, are the result of Congress trying to cut corners to save money rather than a lack of engineering know-how, said Barry B. LePatner, a New York real estate attorney and author of "Too Big to Fall: America's Failing Infrastructure and the Way Forward."

MEMPHIS, Tenn. - Tim Duncan scored the first five points of overtime, and the San Antonio Spurs rallied from an 18-point deficit to beat the Memphis Grizzlies 104-93 Saturday night and move a win away from the NBA Finals.

With the memory of blowing a 2-0 lead a year ago in the West finals to Oklahoma City, when they lost the next four, the Spurs shook off their sloppy play early and pushed the young Grizzlies to the edge of elimination in the first West final played in Memphis.

The Spurs dominated the Grizzlies in the paint, outscoring Memphis 58-42 to offset their 17 turnovers, which the Grizzlies turned into 25 points.
