The speed limit is set at 40 miles per hour. Attention is directed to the viaduct over the Union Pacific Railroad yards. One of the two Interstate 180 spans over the railyards is completed. Traffic is rerouted over this one span, and the old Riner Viaduct is razed. The Riner Viaduct had carried traffic over the railyards since 1929.
Construction continues on the second span.
Although work on the second Interstate 180 bridge was substantially complete by the fall of 1983, cold weather set in before final paving could be accomplished, and thus it was the spring of 1984 before the grand opening could occur. Second span over railyards completed. A park and parking lot adjacent to Interstate 180 are constructed. Signage for Northbound Interstate 180 and U.S. 85 from bottom of off-ramp from eastbound Interstate 80. This is the first of five traffic lights one must cross while on Interstate 180.
