Several large events are prompting road closures and detours in Philadelphia this weekend.
The most significant closures will be in effect during two parades in Center City on Sunday.

Also Sunday, the Hoyu Parade will run through Chinatown, leading to closures at 10th and Race streets and the 1300 block of Wood Street for setup, starting at 9 a.m.
The parade, which runs from 11 a.m. to 2:30 a.m., will cause traffic to be detoured off its route:

-10th Street from Wood to Race streets
