🏃 Chicago Marathon heads up for boaters!
The Bank of America Chicago Marathon takes over the streets this Sunday, October 11, and road closures will impact access to portions of the lakefront and our downtown harbors.
DuSable Lake Shore Drive will remain open in both directions, but several streets providing access to the lakefront—including Monroe, Columbus and Roosevelt—will be closed for portions of the weekend.
If you’re headed to the harbors Sunday, please plan ahead, allow extra travel time and check the official Marathon street closure information before you leave.
