The 30-by-100 foot artwork will depict the hardships undocumented families face in the United States.
The artists especially want to draw attention to a controversial aspect of the Federal dream Act.
They say the proposal would not grant citizenship to 67 percent of the young people who were brought to this country illegally.
"All the images that you are seeing in this mural is their experiences, what they went through in their lives or their parents or grandparents," said muralist Pancho Pescador.
The 67 Dreams Project hopes to pressure Congress to amend the proposal. They want to include a path to citizenship for students who don't want to go into the military or whose families cannot afford a college education.
