Prepare for Summer Construction Season: Sign Up for Notifications on SD511!

South Dakota Department of Transportation’s SD511 Traveler Information System informs travelers, law enforcement, emergency responders, and highway maintenance personnel of conditions that affect travel. Its main purpose is to help the public make well-informed travel decisions. SD511 information includes:
• National Weather Service alerts
• Emergencies and incidents affecting traffic flow
• Special events affecting traffic flow
• Construction and maintenance work zones reported by SDDOT forces
• Commercial vehicle restrictions
• Floodgate messages to convey specific or unique situations.

This allows a longer message with more detail to be pushed to individual routes or statewide. SDDOT maintenance and construction forces feed road reports and road work information into the traveler information system through the Roadway Management System (RMS). Both SD511 and the RMS are provided by Iteris, Inc.
• Dial 511: Users can reach the phone-based 511 system by dialing 5-1-1 on mobile and landline phones throughout South Dakota. From outside the state, the system can be reached at 1-866-MYSD511 (1- 866-697-3511).
• 511 Website: The full-featured SD511 website at provides the same information in graphical and textual form on any modern web browser.
• 511 Mobile Apps: Android and iOS (Apple) mobile applications are available free from their respective app stores.
• My511SD Travel Alerts: Users can subscribe at the website to receive free text and email alerts for road closures, no travel advisories, flooding, and other significant events at specific locations and times of interest to them.
• Rest Area and Port of Entry Kiosks: As of 2021 the SDDOT has been installing kiosks that display travel information at Interstate highway rest areas and commercial vehicle ports of entry.
