Michigan Avenue got a whole lot merrier on Friday night. Mayor Brandon Johnson was among the onstage VIPs as thousands of gathered onlookers stood shoulder to shoulder in crowds that stretched down Michigan Avenue at Millennium Park for the lighting of Chicago’s official Christmas tree.

The 53-foot Colorado blue spruce donated by the Holden-Shaddick family in Logan Square will be wrapped with thousands of lights.

Chicago's holiday season has unofficially arrived, with the city's Christmas tree being lit Friday as a weekend full of holiday events begins.
