More than 800 teams are scheduled to participate in this weekend's Gus Macker basketball tournament downtown.
As of Friday afternoon, Delaware Avenue between Huron and down to Niagara Square to West Eagle Street is closed to traffic.
Crews are setting up and preparing 52 courts.
The streets will remain closed to traffic all the weekend for the tournament and are expected to re-open late Sunday night.
The closures has caused some gridlock on some downtown streets, including parts of South Elwmood near Huron and Delaware and Franklin.
