"Sidewalk Superintendent": Mayor Cecil O. Creal was among dozens of "sidewalk superintendents" who today watched a crane equipped with a clam bucket "chew down" a S. Fourth Ave. portion of the old Allenel Hotel. It will be replaced with a 12-story, $4,000,000 motor hotel, containing 200 guest rooms. Creal has been a staunch supporter of a new downtown hotel and threw city support toward getting the 12-story one. A 150-car municipal carport will be built adjacent to the hotel and near the point the crane is pictured. The new hotel - to be called the Ann Arbor Inn - is scheduled to be completed in November, 1965.
