With the 45th annual Bank of America Chicago Marathon coming up next weekend, street closures have already started.

As of 10 a.m. Monday, Balbo Drive is closed between Columbus and Lake Shore Drive until the end of the marathon Sunday.

More than 40 temporary parking restrictions and street closures are set for the day of the marathon, though additional closures may be added if safety officials deem them “necessary,” the marathon’s organizers said.
