ART GRASBERGER / ARIZONA DAILY STAR 1973 When the city created reversible lanes on some major streets in Tucson, it was intended as a way to ease rush-hour traffic. Traffic flow in the so-called "suicide" or center lane was switched each weekday to flow into the city in the morning for two hours and out at night. On Feb. 23, 1973, it was Broadway's turn to get the new signage, thus eliminating the need to place traffic cones in the road twice a day. This overhead signal was going up near North Park Avenue in front of Rollings Chrysler Plymouth. The reversible lane on Broadway eventually was eliminated in 2001. The last of Tucson's four reversible lanes was removed in 2004 on Grant Road.
