摘要

On May 15, 2004, about 10:04 a.m., mountain daylight time, a 2002 Dodge Durango sport utility vehicle (SUV) driven by a 34-year-old man eastbound on Interstate 70 (I-70) approached the Colorado State Route 470 (C-470) overpass. The driver's 37-year-old wife and their 2-year-old child were also in the SUV. The interchange of I-70 and C-470 was in a temporary traffic control zone for a highway construction project, during which an additional entry ramp and two additional lanes were being constructed for the overpass.
