Emergency Snow Network
During the worst weather or other emergency conditions, Metro may activate its Emergency Snow Network (ESN). When the ESN is activated Metro will severely reduce service to include only core bus routes and shuttles primarily serving key arterials and transit centers. Some neighborhoods and areas of the county may have limited or no bus service because of difficult travel conditions or geography.
When the ESN is activated
The Snow, Ice & Flood map on this page will show blue areas when the ESN is activated. Metro will send alerts to anyone who signed up for Metro Transit Alerts. Customers without internet access should pay close attention to television, radio and other media for weather bulletins that refer to "Metro's Emergency Snow Network."
Each ESN route follows its regular or snow routing as described in its timetable.
The table below lists the origins and destinations for the routes in operation when the ESN is in effect.
