Demolition workers brought down the last remnants of Wilshire Boulevard's historic Ambassador Hotel on Monday as they continued to clear space for a $270-million Los Angeles Unified School District campus.

Only the Cocoanut Grove portion of the 85-year-old hotel remains standing. It will be converted into an auditorium for the site's planned high school.

Workers from Cleveland Wrecking Co. started the demolition in mid-September. Removal of steel, concrete and other hotel rubble should be completed by mid-March, Jeff Droubay, the company's vice president and project manager, said earlier this month.
