What this means

Closures are routes where one or more lanes are completely shut to traffic. The longest-duration items are typically major reconstruction projects (often spanning years) and they affect commutes for months at a time.

What you can do

For multi-month closures, identify a permanent alternate route — Google Maps "explore alternate" will set it as default.
For short-notice closures, follow your state DOT on social media (most run an @StateDOT account) for real-time updates.
If you depend on a specific corridor for work, sign up for your state DOT's email alerts via its 511 portal.
