The Interstate Highways in Nebraska are the segments of the national Interstate Highway System that are owned and maintained by the U.S. state of Nebraska, totaling 482 miles (776 km).[2] The longest of these, by far, is Interstate 80 (I-80) at a length just over 455 miles (732 km).[1] After the system was created in 1956, the state department of roads began construction on its Interstates immediately and upon completion of I-80 in 1964 was the first state to complete its mainline Interstate.[3] With the completion of Interstate 129 in 1977, Nebraska completed its contribution to the Interstate Highway System.[4]
