NY - Sequential vs. Mile Based Exits

[Alps]

The state line is not a "rule". The MUTCD recommends, but does not require, mileposts to reset.

The mile markers on I-495 (Capital Beltway) at the American Legion Bridge do not reset.  They continue to increase to the Springfield Interchange (I-95/I-395/I-495), where they reset to follow the I-95 miles (zero milepost at the North Carolina border south of Skippers) to the Woodrow Wilson Bridge.

Beltways get a different treatment in the MUTCD. Those that are multi-state do get to hold onto their numbers.

Thanks.  I was not aware that beltways got special treatment, though I-435 around the Kansas City, Kansas and Kansas City, Missouri area also has exit numbers that ignore the crossings of the state line.

As does the I-275 beltway in Cincinnati that crosses 2 state lines.

Yet, there are differing beltway cases.

I-255 (IL/MO) carries over the exit numbering and mileposts from Missouri into Illinois and changes only when it becomes IL-255 at I-270; however...
I-270 resets at the Mississippi River and I-270's exit numbering and mileposts carry into I-70 across Illinois.
