Interstate 580 (
I-580) is an
Interstate Highway in northwestern
Nevada. It runs concurrently with
U.S. Highway 395 (US 395) from Interstate 80 in
Reno, to the east leg of
US 50 in
Carson City. Although the freeway has existed in Reno with the I-580 designation since the 1970s, the interstate was signed only as US 395 until the portion between Reno and Carson City was completed in 2012. I-580 is not complete; the highway is expected to be signed between the east and west legs of US 50 in Carson City, however the final phase of freeway construction between Fairview Drive and US 50 west has been postponed several times with an uncertain completion date.
