| 1936 | The Hoover Dam was completed in 1936. Heavily travelled U.S. 93 ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened. | |
| 1966 | In the Providence Journal's auditorium in Rhode Island, BPR Assistant Regional Engineer Robert Kellum conducts a hearing on standards for the Highway Beautification Act of 1965. Pro-billboard speakers contend the proposed standards go far beyond the act's intent. Anti-billboard speakers say "trapped motorists" deserve stretches of highway free of advertisements. Governor John Chafee endorses the standards and promises to comply speedily when they are finalized. | |
| 1988 | The 2-year, $210-million reconstruction of the Dan Ryan Expressway in Chicago, IL, between 31st Street and the Eisenhower Expressway, gets underway. Because of careful planning of alternate routes and an extensive publicity campaign, the closing of two northbound lanes today (and subsequent lane closings) do not result in the widely expected traffic nightmare. A March 2 article in the Chicago Sun-Times about the closing is headlined, "A Breeze!" and begins, "Rush hour? What rush hour?" (See December 5, 1970.)
