At the Wednesday’s city council meeting, Alton Mayor Brant Walker said this phase of work on the park will focus on the parking lot near Argosy Casino Alton. Walker said Phase 8 is the final phase of a 20-year plan to improve Riverfront Park. “As we move forward, we’re going to be able to do more walking, more biking and have more connectivity from the Riverfront to the downtown area,” Walker said.
