One lane of southbound USA Parkway will be closed this week as the Nevada Department of Transportation installs a new roadway landscaping. Southbound USA Parkway will be reduced to a single lane through Friday, from about 9 a.m. to 4:30 p.m. daily. The lane closure will take place from Interstate 80 to approximately one quarter mile south. Motorists should anticipate moderate travel delays and are asked to allow extra travel time. The lane closures are for installation of an approximately 30-foot tall landscape and aesthetic sculpture.
