The attached photo shows the East Grand Blvd approach to the under Jefferson Avenue tunnel to the Scott MacArthur Bridge. I't too bad that the "Do Not Sound Horn" sign is obstructed by the post with the "Belle Isle" and "Jefferson" sign on it. It was, as you can see, a very scenic portion of the blvd.
