Last Leg of Carson City Freeway Opened August 2

The Nevada Department of Transportation opened the last leg of the Interstate 580 Carson City Freeway to traffic on August 2.

Motorists are reminded to drive attentively and anticipate minor lane and traffic pattern changes across the area with the new freeway segment open. Periodic, minor roadside shoulder and lane closures will take place on South Carson Street and the Carson City Freeway for finishing construction.

Prior to construction of I-580, Nevada was one of only a few states without an interstate connecting to the capital city. The new segment of freeway marks completion of I-580 linking Reno and Carson City. Since breaking ground in 2000, construction of the approximately nine-mile I-580 Carson City Freeway has been phased to best utilize available funding. Nearly six million cubic yards of earth were moved, 18 million pounds of reinforcing steel installed and more than $200 million in federal, state and local transportation funds dedicated to construct the freeway between Lakeview Hill in north Carson City and the U.S. 50 junction in the southern part of the city. In December 2015, the freeway was officially dedicated as the Carson City Deputy Sheriff Carl Howell Memorial Freeway. Aimed at increasing traffic mobility and safety with an interstate bypass to help remove through-traffic congestion from downtown Carson City, an estimated 43,000 vehicles daily are projected to use the new southern section of freeway by 2035.
