Alternating directions of I-580 will be reduced to one lane south of Reno beginning Tuesday, Nov. 5 to Thursday, Nov. 7 Nov. as the Nevada Department of Transportation performs routine maintenance to prepare bridge anti-icing systems for winter.
Sections of I-580 will be reduced to one lane from 9 a.m. to 3 p.m. daily Nov. 5-Nov. 7 between Mt. Rose Highway and old U.S. 395A exit 16.
Lane closures will take place on one direction of the interstate at a time.
— Speeds will be reduced to 55 mph through the work zone.
— Drivers should anticipate moderate travel delays.
— The work schedule is subject to change.
Crews will perform routine annual maintenance to clean and refresh the automatic anti-icing systems on four I-580 bridges between Mt. Rose Highway and the Bowers Mansion area. The system has already been converted from a summer water solution to a wintertime potassium acetate anti-icing solution. Crews perform similar winter maintenance to prep the system for winter each year.
The anti-icing system helps delay ice formation on bridge surfaces. As potentially wet, freezing conditions set in, pavement sensors on each bridge automatically activate spray disks embedded within the concrete. Each recessed disk sprays a potassium acetate anti-icing solution. This solution is further spread by traffic, helping delay and reduce the formation of ice. During summer months, the system periodically sprays brief bursts of water to remove roadway dirt from the nozzles.
