JFK in Delaware 40 years ago

I never felt the need to ask why the 12 mile stretch of Interstate 95 that goes through Delaware is known as the John F. Kennedy Memorial Highway. I wasn't aware that he had visited the State to help open the roadway:

Eight days before his assassination, President John F. Kennedy made his seventh and last speaking engagement in the First State. He visited Delaware and Maryland by helicopter on a windy November day to cut the ribbon on the state's new superhighway - I-95. The ceremony was on the median strip at the state line.
