If you don’t receive the confirmation message, please double-check for misspellings or if the number was typed incorrectly. Subscribers can unsubscribe at any time.

The text notification system is designed to provide travelers with an additional communication option for weather-related Interstate closures this winter. This system does not replace, but rather enhances, the opportunity to sign up for text and/or email notifications (along routes of your choice) through SD511.
