Severe Snow Routes
During severe or heavy snow accumulation or icy conditions, Metro will restrict bus service to severe snow routes. Service is limited to major roads only and passengers should anticipate service delays and increased wait times. Customers traveling when Severe snow service is in place should be aware Metrobus may have to suspend all service if road and weather conditions worsen and travel becomes unsafe. Also see light snow routes and moderate snow routes.
