The official dedication for the Martin Luther King Jr. Memorial is scheduled for Sunday in Washington, D.C., two months after Hurricane Irene postponed the original ceremony.

This time around, the pageantry is scaled down -- the expected crowd is estimated at 50,000, down from 250,000 for the August event.

The memorial is a long-awaited monument to the slain civil rights leader and Atlanta’s most famous native son. The four-acre site, opened for visitors in August, is the first memorial for an African-American and sits on the northwest corner of the Tidal Basin. It is surrounded by memorials to former presidents.

The King memorial is more than a 20-year effort started by members of King’s fraternity, Alpha Phi Alpha, and continued by his widow, Coretta, and other leaders.

The dedication, originally scheduled for Aug. 28, the 48th anniversary of King’s “I Have a Dream” speech, will now coincide with the 16th anniversary of the Million Man March on the National Mall on Oct. 16.

The official dedication ceremony begins at 9 a.m. at West Potomac Park. President Barack Obama will deliver remarks and Secretary of the Interior Ken Salazar, members of the King family, and civil rights leaders are expected to participate. The ceremony is free and open to the public. http://www.dedicatethedream.org.

A pre-dedication, hourlong “Morning Joy” program, emceed by journalist and political commentator Roland Martin, begins at 8 a.m. at West Potomac Park.
