Once again please excuse the garbage articles.

The first digit of circumferential interstate roads do not appear to have
any meaning besides allowing for multiple intersecting interstates.
Before I started researching this article in my Rand McNally Road Atlas
I hadn't realized that these route numbers were reused.

Example:
	I-95 north-south along the Eastern seaboard
	     from Houlton, ME, to Miami, FL
	I-395 near Bangor, ME
	I-295 around Portland, ME
	I-495 around Boston, Mass (30-40 miles  out)
	I-295 around Providence, RI
	I-295 around Trenton, NJ  and then south toward Philadelphia
	I-195 east-west across NJ intersecting I-95
	I-895 around Wilmington, Del
	I-695 the Baltimore, MD, Beltway
	I-495 near Washington, DC
	I-295 also Washington, DC
	I-295 around Richmond, VA
	I-br95 near Fayetteville, NC

BTW, I'm sure that this little bit of interstate trivia
has been mentioned before in netnews, what hasn't?, but odd numbered
interstates run north and south while the even numbered ones are east-west.
