Come celebrate the opening of the newly transformed St. Louis riverfront on Thursday, June 2, with Great Rivers Greenway, the City of St. Louis and the CityArchRiver Foundation. The organizations are hosting a “Picnic on the Riverfront” event from 5 to 8:45 p.m. to commemorate the opening of the 1.5-mile stretch of riverfront beneath the Gateway Arch, which includes the newly rebuilt Leonor K. Sullivan Boulevard and extension of the Mississippi Greenway from the Biddle Street Trailhead south to Chouteau Avenue, with protected walking and biking paths. The event will feature St. Louis’ largest-ever community picnic, complete with a 2,016-foot-long community picnic table/chairs. Attendees are invited to either bring their own picnic meal or purchase dinner from food trucks and other vendors. Residents are welcome to explore the Mississippi Greenway and enjoy local music and educational activities for kids. The event begins with a ribbon cutting ceremony at 5 p.m. An interfaith blessing will kick off dinner at 6:15 p.m., followed by an aerial photo of all the picnickers. The event will end with a brief fireworks display at 8:30 p.m. For more information about the event, visit www.CityArchRiver.org/riverfront. The ribbon cutting will happen rain or shine, but the picnic event could be rescheduled in the case of inclement weather.
