Traffic Advisory for 2018 Bank of America Chicago Marathon Weekend Events 

On Sunday, October 7 over 45,000 runners from all 50 states and more than 100 countries will participate in the Bank of America Chicago Marathon – a 26.2 mile course which starts and finishes in Grant Park, winds through downtown streets in the 42nd Ward and Chicago neighborhoods to the north, west and south. Motorists and pedestrians should anticipate delays due to street closures and large crowds. In addition, parking bans will be in effect along the route.

This year, 815 42nd Ward residents will be participating, among the more than 9,000 Chicagoans representing all 50 wards.

The Chicago Marathon begins at 7:20am (wheelchair race), 7:30am (marathon wave 1) and 8:00am (marathon wave 2), and will continue throughout the day. The Start and Finish Line are both located in Grant Park on Columbus Drive. The route extends north to just before Irving Park, west to Damen Avenue and south to 35th Street.

Traffic Impacts for Chicago Marathon-Sunday, October 7
Anyone traveling throughout downtown and the various neighborhoods along the route should allow extra time and expect delays. Motorists should consider alternate routes – such as the expressway system – to avoid the impacts of the race. Some street and lane closures are already in place in the Grant Park area, including Columbus from Roosevelt Road to Balbo Drive and Balbo Drive from Columbus to Lake Shore Drive.

By Saturday, expect additional Grant Park street closures on Columbus, Balbo, Congress, Jackson and Monroe, with most streets in Grant Park reopening by Monday morning. Street closures along the route will begin at approximately 7:00 a.m. on Sunday and are anticipated to be reopened by 4:30 p.m. or when it is deemed safe to do so.
