A riddle this time:
I affect every other that crosses me, but not necessarily every one I touch. And I’m the only one in Montreal that does this. Or at least I was before the merger.
What am I? What do I do to others? And who is the other that’s (kinda) like me?
UPDATE: Three of you independently got the first two right: It’s St. Laurent Blvd., which splits the island between East and West. Any streets that cross it (actually, any streets that can be found on both sides, whether or not they actually cross) get East and West designations. Those that are only on one side (even if they intersect St. Laurent) don’t have them.
UPDATE (June 2): Michel K gets the last part right: Gouin Blvd. in Roxboro splits three streets – 3rd Ave., 4th Ave. and 5th Ave. – into North and South. (Two others, 1st Ave. and 2nd Ave., have North designations but no southern counterpart.)
Kate also notes Montreal West, which is split North-South by the tracks.
