It’s going to be quite a colorful weekend.

The Three Rivers Arts Festival in Pittsburgh is celebrating its 60th year on the books. More than 500,000 visitors are expected to flood the streets of Pittsburgh to experience public art and music. The festival will last through this weekend and next weekend.

All week, many vendors have been setting up their tents to prepare for the festival. Tents line downtown Pittsburgh, which ultimately means there are a lot of restrictions regarding street closures.

Some of the street closures currently in place include two lanes between Commonwealth between Penn Avenue Extension and Fort Duquesne Blvd.

Several dozen artists coming in for the festival will also experience some traffic restrictions. From 8 PM to midnight on June 11, 13, and 16th, two lanes of Penn Avenue Extension outbound will be closed between Stanwix Street and Commonwealth Place. All lanes between Liberty Avenue Extension inbound from the Gateway Center Parking Garage to Stanwix Street will be closed.

There will also be some parking meters that are unavailable, so if you’re planning to park on the street, keep this in mind.

Because there are so many road closures to keep up with, you can check out the full list of closures and how that might affect your travel route in the coming days on CBS Pittsburgh’s website.

The festival is free and open to the public.
