Here are three aerial photographs, the first taken in 1952, the second the same but with landmarks labeled, and the third taken last year, showing the Covington Bypass, where U. S. 190 loops around through Collins Blvd to the beginning of La. 25, and then heads west towards Hammond. Click on the images to make them larger.
