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."

CHICAGO - All that tinkering with the power play, all the practice time and the tweaked combinations finally paid off for the Chicago Blackhawks when they needed it the most.

Jonathan Toews and Andrew Shaw scored with the man advantage in the second period, and the Blackhawks avoided elimination with a 4-1 victory over the Detroit Red Wings on Saturday night in Game 5 of the second-round playoff series.

Shaw added his third career playoff goal in the third as the Blackhawks stopped the Red Wings' three-game winning streak by creating chaos in front of Jimmy Howard, who had shut down Chicago's attack while moving Detroit to the brink of the Western Conference finals.
