If you're driving through the center of Miami tonight, you need to take a close look at the map below.
The monthly group bike ride called Critical Mass is taking place again. Cyclists will be riding over 13 miles around Miami starting at Government Center and ending at Grand Central Park.
The Miami event usually draws a couple thousand cyclists and can back up traffic. The route changes every month.
Fort Lauderdale's Critical Mass will take off from the War Memorial Auditorium.
Both events list 6:30 p.m. as the gathering time and 7:00 p.m. to 7:15 p.m. as the start time. Whether you're interested in avoiding the group bike ride or joining in, you can learn more about Miami's Critical Mass at the blog Miami Bike Scene. The map of today's route is below.
