Dive Brief:
Kiewit Meridiam Partners found computer errors were responsible in part for flooding a low-lying portion of I-70 that nearly submerged cars as heavy rain slammed Denver this summer.

The contractors were tapped to design, build and maintain the 10-mile, $1.2 billion Central 70 project that runs through northeast Denver.
