Description

The Nebraska Department of Transportation is responsible for the daily maintenance and operations of the State Highway System, which includes the Interstate Highways in Nebraska. These highways are built to Interstate Highway standards, as such, they're all freeways with minimum requirements for full control of access, design speeds and other characteristics. Speed limits along the Interstates within Nebraska range from 60 miles per hour in the Omaha Metro area to 75 miles per hour along the majority of I-80 outside of Lincoln and Omaha.^[5]
