ST. LOUIS (KPLR) - St. Louis is throwing a party at the Arch Grounds Thursday afternoon to mark the completion of one part of the CityArchRiver renovation project: a brand new Leonor K. Sullivan Boulevard along the riverfront.

The 1.5-mile stretch of road that runs beneath the Gateway Arch was raised two feet to prevent flooding from the Mississippi River.

The new roadway features a bike path, benches, flags, power outlets, and even a stage.

Missouri Governor Jay Nixon, St. Louis Mayor Francis Slay, and Congressman William “Lacy” Clay will be on-hand to cut the ribbon and officially open the boulevard at 5 p.m. A community picnic will follow at 6 p.m. The celebration will conclude with an evening fireworks display.

While this part of the CityArchRiver project is complete, there's still more work underway. Crews expect to complete the north and south ends of the Arch Grounds this fall. Everything else, including the Arch Museum, is slated to be finished in the fall of 2017.
