The use case would be to distinguish between onramps in routing and
guidance. The onramp entrances can be close together, so it helps
tremendously if you can say 'turn right onto Interstate 215 West'
instead of just 'turn right onto Interstate 215'.

When tagging boundaries, I think you'll find it worthwhile to look at the

incorporated governmental units by state. It's is a comprehensive listing

The direction of a US Interstate isn't necessarily the compass direction of
the road.
For example, this chunk of I-94 is facing south, but it's still eastbound
I-94.

One could argue that even two lane highways could benefit from directional
relations.

It is unlikely that all access to these types of roads could be tagged. And it
might be nice if the routing software says you should be on US 101 South and

However, in some cases the directions change as the highway goes on,
especially for loops: I-610 in Houston, Texas, changes from north/south

True also of the westbound Ventura Freeway in Los Angeles which is officially
US101 North.
There is a portion of I10 through Phoenix which runs north/south too.

Yea, I realized that as well. There's even a section of I-80 / I-580
in Berkeley, CA where the directionality of I-80 and I-580 is
opposite... http://goo.gl/maps/XROab (The actual compass direction is
more like N/S on that stretch.)

From
http://en.wikipedia.org/wiki/Interstate_Highway_System#Primary_.28one-_and_two-digit.29_routes_.28contiguous_U.S..29:
In the numbering scheme, east-west highways are assigned even numbers and
north-south highways are assigned odd numbers. Odd route numbers increase
from west to east, and
Just to add, three-digit routes tend to be either regional or be
loop-shaped, where the designated direction changes.

the ferry routes and the ferry access roads in the highway route relation.
I also have done some edits to ferry terminals, adding a way for each lane

Thanks for all your input. For the interstates it seems to be somewhat
straightforward, at least for the two digit ones as Ian indicated. It
gets tricky when you enter the realm of three-digiters and US and
state routes... That is where explicit directionality would be
helpful.

California gives State, US, and Interstate roads unique signed numbers

is close enough to State Road 64 to cause frequent confusion.
