Brief overnight ramp closures will continue on U.S. 395 in the North Valleys through the coming week as the Nevada Department of Transportation tests and activates new wrong-way driver detection systems. Individual freeway ramps will intermittently be closed for up to four hours weeknights between 9 p.m. and 5 a.m. through approximately Jan. 15. NDOT currently places “Wrong Way” signs on all freeway ramps to notify drivers errantly entering in the wrong direction. As a pilot program, NDOT installed additional flashing warning signals and detection systems on 20 U.S. 395 ramps in the North Valleys.
