The International Shriners definitely know how to have fun, and they will do that on Tuesday evening when they hold a parade in downtown Minneapolis.

More than 15,000 members of the Imperial Session of the Shriners International are in town for their annual business meeting. This evening, they'll clown around in their vibrant costumes, play an array of musical instruments and race miniature cars down Hennepin Avenue.

The parade steps off at 7:30 p.m. It begins at Loring Park and follows Hennepin Avenue to 5th Street. That, of course, means traffic disruptions and detours for Metro Transit routes.

Here is what will be closed:

Beginning at 7 p.m. and lasting until about 10:30 p.m., Hennepin Avenue will close from Dunwoody Boulevard/Lyndale Avenue to Washington Avenue. During this time, a number of cross streets will also be closed, although traffic will be able to cross Hennepin Avenue at 4th, 5th, 10th, 11th, and Maple Street/16th Street.

Metro Transit says the following routes will be on detour in downtown Minneapolis starting at 7:15 p.m. Tuesday: 3, 4, 5, 6, 7, 9, 12, 14, 18, 19, 22, 61 and 675. Here are the details along with a parade route map.
