Hello, I am wondering how you can map that when you enter a highway from a specific ramp you cannot exit at the next one. Please see http://osm.org/go/ZXCt9WHU-- where it is forbidden driving from I-94 east to M-10 to exit M-10 at exit 4C. Is what I did in relation http://www.openstreetmap.org/browse/relation/275622 correct? Thanks, N.
