Monday, July 25, 2005 · Last updated 10:14 p.m. PT Truck carrying dynamite overturns on I-405 THE ASSOCIATED PRESS BOTHELL, Wash. -- A tractor-trailer rig carrying nine cases of dynamite overturned Monday on Interstate 405 near this northeast Seattle suburb in an accident that slowed but did not stop rush-hour traffic. The big truck had been changing lanes on southbound I-405 at about 5 p.m. when it turned hard to the right to avoid stopped traffic, clipping another vehicle in the process, State Patrol spokesman Trooper Lance Ramsay said. The truck then clipped the guardrail and rolled onto its side. Neither the truck driver nor anyone in the car was injured, Ramsay said. Ramsay could not say precisely how much dynamite was involved but he noted it posed no hazard because it was not hooked to blasting caps. At about 8:15 p.m., state authorities closed both northbound and southbound lanes of I-405 as well as the street that runs beneath it at that point, Ramsay said. The dynamite was offloaded into another trailer and the truck was then pulled upright and towed away. The highway reopened about 9:30 p.m., he said.
