About this app
The Mass511 app is the Massachusetts Department of Transportation's official traffic and traveler information app. The Mass511 app, new and improved in 2022, provides up-to-date traffic information for interstates, U.S. routes and state highways across Massachusetts. FEATURES: • Hands-free, eyes-free audio notifications of traffic events while you drive • A zoom-enabled map with tappable traffic event icons and surrounding camera views • Near real-time updates on traffic incidents, construction, weather and road closures • Manage My Mass511 personalized accounts including saved routes, areas, and camera views and email and text alerts • View current traffic speeds • View traffic cameras throughout the state. Sign up for a My Mass511 account to save cameras for easy access. • Access to additional traveler information resources NOTE: Continued use of GPS running in the background can decrease device battery life. The primary responsibility of every driver is the safe operation of their vehicle. While traveling, mobile communication devices should be used only when the motor vehicle is at a complete stop, off the traveled portion of the roadway. Do not text and drive (it's against the law) or use this app while driving. App developed by Castle Rock Associates https://www.castlerockits.com.
