The 200 traffic signals in Montgomery County that were affected by last night’s storm are located along the Rockville Pike/Route 355 corridor north of the Beltway in the Derwood, Rockville, Germantown, Gaithersburg and Damascus areas.

The signals are operating, cycling red, green and yellow. However, the signals are not synchronized with each other and have not switched to rush hour mode, which provides more green light time to the predominant flow of traffic.

Residents should expect traffic delays and are urged to take public transportation or avoid the affected portion of Rockville Pike if at all possible.
