South Street Headhouse District announces the return of South Street Spring Festival on Saturday, May 6, 2017, from 11:00AM to 8:00PM. Rock your way into the summer season with a giant, all-ages outdoor block party that will take over the street from South (between Front and 8th) and run along Headhouse Plaza. Last year, over 58,000+ people came out to enjoy the music, food and fun in the sun. Mark your calendars as the city’s largest block party is back!
