In the late 1950s the construction of what was then referred to as Route 3 was highly controversial. It conveniently crossed through the western and northern edges of Downtown Omaha, two areas city leaders had considered "blighted" since the 1930s. The heavily Catholic, ethnic European neighborhoods the route went through rallied against the demolition of their homes, and the city's parks advocates provided resistance as well. Eventually the Interstate planners won out, and the city's historic Jefferson Square was demolished, as well as dozens of homes along the route.
