Eastbound lanes of I-70 reopen in Denver after crash at Quebec Street

The eastbound lanes of Interstate 70 were closed at Quebec Street in Denver on Monday afternoon for several hours. The crash closed all three lanes of traffic and the express lane. By 6 p.m. the lanes were starting to reopen.

The CBS News Colorado helicopter flew over the scene which showed one vehicle on its roof, another crashed vehicle in the left shoulder of the interstate and at least two other vehicles pulled over in the crash site. 

There were three fire engines at one time and at least one ambulance on scene in addition to several police vehicles. Traffic was exiting onto Quebec but there were big backups in the area. 

What led up to the crash is being investigated.
