Beeline Highway in Palm Beach County is of course completely unrelated to the Beeline/Beachline Expressway in central Florida.
SR528 used to be a connecting road that ran from I-4 to just east of McCoy Jetport, the predecessor of Orlando International Airport. Martin Andersen was the publisher of the Orlando Sentinel newspaper and was a proponent of getting an expressway-type road over to Kennedy Space Center on the coast. This led to the creation of the Orlando-Orange County Expressway Authority whose mission was (and continues to be) to build toll roads. The 528 was the first followed by the 408 (East-West Expressway), the 417 (Central Florida Greeneway), the 429 (Western Beltway) and now the 414 (Apopka Bypass).
