Project Name: USH 20 (including parts of the Grant, Blue 
Pole and Antelope Trial highways)
Project Location: South Sioux City to the 
Nebraska/Wyoming state line
Project Client: Nebraska State Historic Preservation 
Office. 
Project Summary: Much of the USH 20 route across northern 
Nebraska had previously been part of the Blue Pole, Grant or Antelope Trail 
highways. It appears, however, that USH 20 was the first roadway designated to 
cross the entire northern portion of the state, having been named when the 
federal highway system was identified in 1926. Indeed, USH 20 was part of a 
national roadway that came to be known as "the last transcontinental." Since its 
designation, USH 20 has changed much in Nebraska. Parts of the old road have 
been abandoned, while others portions carry only local traffic. But it remains 
today, an artifact of Nebraska’s transportation history.
Survey Results: Over 150 surveyable examples of roadside 
architecture, or of the old roadway itself, were identified on the alignments 
studied for the USH 20 project. All properties were appropriately noted and 
included in the record and report provided at project conclusion.
