Interstate 35 is a long highway that runs from Texas to Minnesota, and different segments close and reopen at different times, usually because of construction or weather. To know exactly when I‑35 will reopen for you, the specific state and nearby cities or exits are crucial.

What’s known right now

  • In Iowa and southern Minnesota, a recent winter storm closure between Ames and the Minnesota state line was scheduled to reopen early Monday afternoon after crews finished snow and ice removal.
  • Around San Antonio, Texas, various I‑35 ramps and mainlane closures are tied to the ongoing I‑35 NEX construction project, with some ramps reopening on specific December dates and others remaining under long‑term closure.

Why the answer depends on location

Closures on I‑35 are usually:

  • Weather‑related (blizzards, ice, low visibility), where reopen times can change hour‑by‑hour based on conditions.
  • Construction‑related (like I‑35 NEX in San Antonio), which follow planned schedules but can shift due to project progress.

Because of this, the same day might see I‑35 open in one state and closed in another.

How to get your exact reopening time

To get a precise answer for when will I‑35 reopen in your area:

  • Check your state’s DOT site (for example, Iowa DOT, Minnesota DOT, or TxDOT all publish live I‑35 updates and closure notices).
  • Use a live traffic map (Google Maps, Waze, or state 511 services) and zoom into the stretch of I‑35 you care about to see whether it is marked as closed or reopened.

If you share which state and the nearest towns or exits, a more specific reopening window can be inferred from those official updates.
