Two road workers died in a traffic crash Tuesday in the Highlands Ranch area when an SUV came careening off of C-470 and through a construction zone.
The crash happened about 11:55 a.m., said Nate Reid, a Colorado State Patrol spokesman.
A 2007 Tribeca Subaru was westbound on C-470 when the driver exited at Broadway and lost control of the SUV, Reid said.
The SUV ran up a grass embankment, about 50 feet, before quickly running back down the hill and hitting the two men who were working in a coned-off zone.
The SUV then hit a Honda Pilot that was heading north on Broadway.
The two workers died at the scene.
None of the people involved were identified.
The driver of the SUV and a passenger, and the driver of the Pilot, were taken to a local hospital to be treated for minor injuries.
The two victims were part of a crew that were doing work on the underside of the C-470 bridge spanning Broadway.
About two hours after the incident, family members of the victims arrived at the scene.
One woman in her mid-20s ran toward the construction zone. She dropped her purse and her hat fell from her head as she cried: "Where is he? Where is he?" Troopers with the state patrol intercepted the woman and she collapsed, crying.
A short time later a second woman was escorted to the area.
The workers who died were employees of Concrete Works of Colorado, Inc., a company spokesman confirmed Tuesday afternoon. He declined further comment.
The company, founded in 1978, has contracts throughout the metro area, according to its website.
South Broadway was closed in both directions, from County Line Road to Dad Clark Drive, by the crash.
Preliminary indications are that alcohol was not involved in the crash. Investigators are working to try and determine how, or why, the driver lost control.
Despite construction zone precautions, including zoned-off areas, cautionary signs, slower posted speeds and steep fines for violating drivers, road work remains a dangerous job.
In 2011 there were 830 work-zone crashes reported in Colorado, according to the Colorado Department of Transportation.
Before Tuesday's crash, at least six CDOT workers were killed in work-zone crashes since 2000. In all, the state highway department has lost 58 employees in the line of duty since 1929.
