A 1' diameter, matte chrome, opaque sphere hovering between the Highway, reported to the local police department that day

I was driving to work in the morning, taking a phone call to set up a medical appointment. As I approached County Rd. I overpass there was what appeared to be a floating object between the two sides of the highway (or above the wild grass that grows between the East & West -bound traffic). My brain thought, Oh weird, a balloon must be floating down from the sky. However, it stayed precisely where it was in space while I approached at around 65 mph in the fast lane. My vehicle drove under the overpass and I noticed it was spherical, unlike a balloon, with no visible markings, propeller mechanisms, seams. The object was perfectly still regardless of light rain. I announced to the medical administration staff what I was seeing. It had all of my attention and observation. I felt curiosity and awe at how inorganic and perfect it appeared. When I was passing the object and it was directly outsdide of my driver window, it lifted/moved up 9 inches and continued hovering still in that new spot in space. I looked over my shoulder to track it, then had to look in my rearview mirror. Due to the overcast skies and color of the sphere it was hard to see the further that I drove passed. I made up my mind to go back to get footage, but did not spot it, nor when I backtracked yet again to head in the original direction. A coworker implored me to report the incident to the local authorities. Deputy Krueger called me back and took my testimony around shortly after 10AM
