In 1890 the railway was routed through Brandon, and Bloomingdale began to decline as businessmen like D.J. Galvin, who owned a feed store on the property that is now Mulrennan Middle School, moved to Brandon for access to all the benefits provided by the railroad. In 1910, the post office closed. In 1920, the school closed and the students were sent to Brandon instead. The community declined, or at best remained stable until the 1960s, when it became a bedroom community for Tampa.
