More traffic signals are now working at Tahoe-Reno Industrial Center east of Sparks. 

Signals at Waltham Way and USA Parkway are now in operation, following the completion of the signal at Sydney Drive last fall. 

Storey County says the goal is to help ease congestion and improve safety for drivers.

It will help manage heavy peak-hour traffic, enable safer left turns, and improve the overall flow for vehicles traveling to and from I-80.
