Chicago's annual "Bike the Drive"

Over Labor Day weekend, for the last 20+ years, Chicago has closed DuSable Lake Shore Drive to motor vehicle traffic, so bicyclists can "Bike the Drive," which is sponsored by the Active Transportation Alliance.

It's similar to "Open Streets" events which also focus on pedestrians as well as bicyclists. 

Bicyclists enjoy the ride on North DuSable Lake Shore Drive through Lincoln Park on Sept. 3, 2023, during the 22nd Bike the Drive, an annual event hosted by Active Transportation Alliance that closes the roadway to vehicles from Bryn Mawr to 57th Street for the morning.
