Indiana – Memorial Day traditionally marks the start of the summer travel season in Indiana. And whether you’re attending the Indianapolis 500, vacationing, visiting family and friends, or just passing through, INDOT urges drivers to plan extra travel time, to stay informed on road conditions, and to drive safely. Most highway maintenance activities and construction projects will halt work during the holiday weekend to increase mobility and safety. Some restrictions and reduced speed limits will remain in place due to ongoing road construction. Learn about traffic and road conditions, crashes and construction on state highways by dialing 511 from a mobile phone, or by using the INDOT mobile app.
