Rick Kraft untied his work boots, pulled off his Comcast shirt and tiptoed into the Mississippi River. A man in a half-submerged red car, blood oozing from his mouth, was stuck with one leg out the window.
Ten minutes earlier, Kraft had been heading home to West St. Paul after a day of installing and updating cable, phone and computer lines to homes in Minneapolis.
Stuck in the gridlock on 35W, Kraft exited at 4th Street, planning to skirt the jam on city streets. He heard a deafening thud at a University Avenue red light and looked over. He couldn't figure out why they'd demolished the bridge.
Zooming up a closed exit ramp, Kraft drove about 6 feet onto the bridge, before backing up and parking on the ramp. His mental tug-o-war was underway, as he measured risk to himself against a desire to help victims.
"If I get hurt, I'll just add to the pandemonium and I had my two daughters to think about," he said. "I was trying to wrap my head around how big a catastrophe it was."
He climbed down the river bank, found a gap in a crushed freight train and grabbed a two-by-four to measure the depth of the water.
Kraft, now 30, had no trouble walking barefoot over chucks of concrete toward the man with the bloody face. As a kid growing up in Maiden Rock, Wis., he'd climbed plenty of riprap.
He wasn't sure if the red car was teetering and might roll under the wreckage. That's why he took off his boots. "I was prepared to swim."
