Lane closures begin for I-580 sign changes in northern Carson City, Washoe Valley and Reno
Submitted by Jeff Munson on Sun, 04/19/2020 - 4:10pm
Lane closures will take place beginning Monday, April 20 as the Nevada Department of Transportation changes exit numbers on Interstate 580 between northern Carson City and the Reno spaghetti bowl.
Previously, daytime shoulder closures were in place as new sign foundations and ground-mounted signs were installed. The following lane and ramp closures will now take place on small, intermittent sections of both directions of I-580 between the Reno spaghetti bowl and northern Carson City as exit number sign panels are replaced on large overhead exit signs:
Daytime lane closures will take place 7p.m. to 5a.m. daily April 20-21 on both directions of I-580 between northern Carson City and South Virginia Street exit 61.
Beginning April 22 through the first week of May, overnight lane and ramp closures will take place 7p.m. to 5a.m. nightly Sunday evenings through Friday mornings on small, intermittent sections of both directions of I-580 between the Reno spaghetti bowl and South Virginia Street exit 61. Overnight ramp closures will take place on one ramp at a time, with detours available. No consecutive ramps will be closed at the same time.
The construction schedule is weather dependent.
Exit numbers for all I-580 exits between the Reno spaghetti bowl and North Carson Street exit 43 will change. The physical roadway exits and names will remain the same, but roadside exit number signs and small exit number sign panels at the top of overhead signs will be changed at each exit to reflect the new exit numbers.
The current exit numbers range from 43 to 68B, and will be replaced with new, lower exit numbers corresponding with roadway mileage, beginning at the northern end of the I-580 Carson City Freeway and progressing north to the Reno spaghetti bowl. I-580 exit numbers were changed last fall in Carson City.
The exit numbers are being changed per federal requirements. Federal guidelines require interstate exit numbers to reflect mileage specific to that corridor. Current I-580 exit numbers reflect U.S. 395 mileage beginning at the Nevada-California state line near Topaz Lake.
Now that the I-580 connection from the Reno spaghetti bowl to south Carson City supersedes the previous U.S. 395 designation, exit numbers are being changed to reflect interstate mileage beginning at the I-580 junction with south Carson Street and ending at the Reno spaghetti bowl.
NDOT encourages organizations to update any advertising, mapping or other logistics as existing I-580 exit numbers change.
First responders will be alerted prior to specific exit number changes, and electronic roadside signs will be placed during exit number sign changes to alert drivers of the change.
Information and a map of updated interstate exit numbers is available at www.nevadadot.com/exit.
NDOT and its contractors continue vital highway construction and maintenance activities upkeeping Nevada’s transportation system for essential travel and supply chain deliveries. The department actively practices COVID-19-related public health and safety protocols, including social distancing of six feet or more and restricting groups to 10 or less, thereby keeping our team, families and communities safe and connected.
