Unidentified Object Hovering over Interstate 264, Norfolk, Virginia

I was driving to work on 7 February 2007, from Virginia Beach to Norfolk Virginia.  As I was driving, coming close to my exit (Interstate 564).  
As I was driving, this bright flourescent light in the sky caught my attention.  As I continue to drive, I observed this object in the sky.  I could not stop, because I was in the far left lane, and traffic was heavy that morning.  
At first, I thought it was a helicopter, shining it searchlight, but this flourescent light was too soft (I wasn't blinded by it).  This light shone exactly like a strobing light, but no flicker was present when it caught my attention in the sky. This object appeared to be a long cylinder (cigar shaped). 
As I continue to drive and look at the flourescent light, it was very soft to my eyes.  I also caught a glimpse of a red light under the belly of the object (center of the object).  I tried to determine if this was a helicopter, but I would know if this was a helicopter by the sound they make, but this object produced no sound.  
It maintain it stationery position for at least 1.5 minutes before I had to exit Interstate 264.  I tried to see if the object from Interstate 564, but wasn't able to see the object anymore from my new position.
