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."

BOSTON - Tuukka Rask stopped 28 shots, Gregory Campbell scored twice and the Boston Bruins beat the New York Rangers 3-1 in Game 5 on Saturday to advance to the Eastern Conference finals.

Recent call-up Torey Krug scored his fourth goal of the series for Boston, which reached the third round of the NHL playoffs for the second time since 1992.

The other was 2011, when the Bruins won the sixth Stanley Cup in franchise history.
