Participants walked 10 kilometers through West Hollywood and the Fairfax district. The walk began at 10 a.m. at West Hollywood Park.
The $3,005,014 raised Sunday increases the total raised to fight the disease in Los Angeles County since the walk's inception to more than $72 million, according to Craig E. Thompson, AIDS Project Los Angeles' executive director.
Several celebrities were in attendance, including current "Dancing With The Stars" contestant Carson Kressley and former contestant Cloris Leachman.
The money raised from the event helps treat as many as 10,000 AIDS patients locally.
Traffic delays were expected in the area. To get more information and to see a map of the route, visit www.aidswalk.net/losangeles.
