It's a pretty poor grainy, low-res photo, but from the short robust body shape, keeled scales and pattern remnants I can just make out, it does seem to be a melanistic form of Eastern Hognose. They can be EXTREMELY variable. They can range from very vividly colored and patterned, to a very solid black, or anything intermediate of this.

I have personally captured a solid black(melanistic) Eastern Hognose in Ft. Pierce, Florida as I was getting off I-95 that looked just like the one in this photo below.
