Minor single lane closures and pedestrian travel shifts will take place on Keystone Avenue near Interstate 80 through mid-February, as the Nevada Department of Transportation installs enhanced pedestrian sidewalk ramps. Crews will work on one side of Keystone Avenue at a time while pedestrian traffic is detoured to the other side. Pedestrians will be able to use marked signalized crosswalks at West 7th and West 5th streets to cross to the sidewalk on the opposite side of the street while traveling underneath I-80. Intermittent single lane closures will also take place weekdays between 9 a.m. and 3:30 p.m. Only one lane will be closed at a time, and no lane closures will be in place during the evening rush hour.
