There will be overnight lane closures through Thursday, on I-580 just south of the Reno spaghetti bowl as the Nevada Department of Transportation repairs roadway concrete barrier rail. Both directions of I-580 just south of the spaghetti bowl will be reduced to two lanes between 8 p.m. and 5:30 a.m. through Feb. 1st, as more than 15 feet of median barrier rail damaged in a crash is replaced. The road work is taking place during overnight hours to reduce impact to commute travel.
