Interstate 80 (I-80) in the U.S. state of Nebraska runs east from the Wyoming state border across the state to Omaha. When it completed construction of the stretch of I-80 spanning the state on October 19, 1974, Nebraska was the first state in the nation to complete its mainline Interstate Highway System.
Contents
Nebraska has over 80 exits along Interstate 80. According to The New York Times there are several notable tourist attractions along Nebraska's section of I-80. It is the only Interstate Highway to go from one end of the state to another, as Nebraska has no major north–south interstate route. Except for a 3-mile-long (4.8 km) portion of I-76 near the Colorado state line, I-80 is the only primary (two-digit) Interstate Highway in Nebraska.
History
Built along the pathway of the Great Platte River Road, I-80 in Nebraska follows the same route as many historic trails, including the Oregon Trail, the California Trail, and the Mormon Trail. Starting in 1957 after federal funding was allotted, Nebraskans began planning their Interstate construction. Led by the Nebraska State Highway Commission, there were hearings across the state to decide where the route was going to be. Aside from the federally mandated "control points" in Omaha and Scottsbluff, the route could vary across the state. Dozens of meetings were held in Grand Island, Kearney, and North Platte, among other locations. The commission addressed issues of whether the highway would be north or south of the Platte River or whether it would follow U.S. Highway 30 US-30. The South Platte Chamber of Commerce and various cities were very active in these sessions, and debate over where the Interstate would be constructed continued into the 1960s.
After the first contract for building the Interstate was awarded in 1957, a 6.5-mile (10.5 km) section near Gretna was the first section to be completed that year. The first long segment to be opened was a 50-mile (80 km) section between Dodge Street in Omaha and the West Lincoln interchange in Lincoln in 1961. During a "Golden Link" ceremony, the last section of I-80 in Nebraska was completed when a brass connector was inserted in the roadway near Sidney on April 1, 1974. This was designed to emulate the golden spike ceremonially used to complete the Trancontinental Railroad in 1869.
The total length of the Nebraska section is 455.27 miles (732.69 km) long, and was completed at a cost of $435 million.
Legacy
The beginning of the I-80 construction in Nebraska in 1957 led the Nebraska Legislature to split the Department of Roads and Irrigation in order to create three separate agencies in the state, including the Department of Motor Vehicles, Department of Water Resources and the Department of Roads, which was the first Nebraska agency solely responsible for highway planning, construction, and maintenance in Nebraska history.
Interstate construction led the state to focus on other highways in Nebraska, as well. Surfaced shoulders, new safety sections beyond shoulders and other developments across the state were attributed to the influence of the Interstate. The 1965 state legislature also authorized a study of the needs of every public road in Nebraska, including state highways, county roads, and city streets.
Speeds
The following are speed limits that have existed on I-80 in Nebraska since it was opened in 1957.
Designated sections
The entirety of the Interstate Highway System was named the "Dwight D. Eisenhower System of Interstate and Defense Highways" in 1990, and the first signage in Nebraska was posted in 1993. Several sections of I-80 in Nebraska have special designations. The I-80 intersection with US-34 has been designated a "Purple Heart Memorial Highway", and South 108th Street bridge over I-80 in Omaha has been designated the "Purple Heart Bridge", both in honor of all recipients of the Purple Heart. A section of I-80 in Nebraska is also designated as a Blue Star Memorial Highway.
Details
In Nebraska, I-80 has 82 interchanges, 442 bridges on or over the roadway, 25 rest areas, and one scenic overlook, each spaced 35–50 miles (56–80 km) apart for convenience. The I-80 rights-of-way in Nebraska feature 28 types of grasses and forbs, 31 types of shrubs, 12 varieties of coniferous trees, and 39 types of deciduous trees are planted on the median of I-80 in Nebraska. There are also 570 informational and directional signs along the way. Mile markers with the interstate shield are posted every 2⁄10 mile (0.32 km) beginning at mile 379.0 going east.
Auxiliary routes
Interstate 80 has three auxiliary routes in Nebraska. One is a loop around the city of Omaha, one is a loop through the city of Omaha, and the other is a spur into Lincoln.
