NDOT to start changing exit numbers on I-580 from Carson City to Reno

Nevada Appeal staff report

The Nevada Department of Transportation is alerting drivers and organizations to prepare for an upcoming change to exit numbers on Interstate 580 from South Carson Street in Carson City to the Reno Spaghetti Bowl.

NDOT encourages organizations to prepare to update any advertising, mapping or other logistics as existing I-580 exit numbers change beginning this summer. Drivers in Carson City will see the exit numbers change beginning this summer. I-580 exit numbers from Washoe Valley to the Spaghetti Bowl are anticipated to change beginning in the fall.

The current exit numbers range from 38 to 68B, and will be replaced with new, lower exit numbers corresponding with roadway mileage, beginning at the southern end of the I-580 Carson City freeway and progressing north to the Spaghetti Bowl. The roadway names will remain the same.

The exit numbers are being changed per federal requirements. The federal Manual on Uniform Traffic Control Devices ensures freeway signs and mileposts are consistent nationwide to convey a clear message and help guide, warn and regulate traffic. 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 the I-580 connection from the Reno Spaghetti Bowl to south Carson City is complete and 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 Spaghetti Bowl.

Small exit number sign panels at the top of overhead signs will be replaced, as well as roadside exit number signs at each exit to reflect the new exit numbers.

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.
