The start of a new memorial project for assassinated U.S. Senator Robert F. Kennedy at Washington D.C.’s RFK Stadium was announced by the District of Columbia’s Mayor Muriel E. Bowser, the senator’s family members, and Events DC, on May 17.

The memorial project is part of an overall plan for the RFK Stadium complex, a $500 million project spearheaded by New York City–based OMA. The proposal involves demolishing the current stadium and its parking lots, transforming the site into a 350,000-square-foot recreation and sports complex complete with three ball fields and a 47,000-square-foot market selling groceries.

The memorial will honor the late senator, serving “as a place of remembrance and a place of teaching and practicing the civil rights and equality ideals Robert F. Kennedy championed,” Events DC said in a statement to The Washington Post.

The 190-acre site sits on federal government land and will be tied to neighboring Kingman Island and the River Terrace neighborhood by three new pedestrian bridges. Events DC, the city’s official convention and sports authority, will be funding half of the project while city, hotel tax revenue, and team leases will cover the rest.

“On behalf of my family, we are delighted… to begin this journey… in tribute to my late grandfather,” Maeve Kennedy McKean, the senator’s granddaughter said in the Events DC statement. “My grandfather lived his life every day in the service of others.”

Officials hope that the redevelopment of the new stadium site and the memorial will begin and finish over the next five to seven years, according to Events DC. The D.C. United soccer club currently occupies the stadium and will continue to do so for another year, until the new BIG-designed stadium is completed.
