I am a new owner and am North of the bridge. I will let the other members "chime in" BUT you're complaining about $15.00 U.S.... You are paying a "toll" for the cost of the bridge. Not too long ago there was some type of "raft" that took you across. Hey forum members; how much did that cost?
The ONLY complaint I have about the toll is that you no longer can buy a round trip or a "bunch" of trips. I used to purchase $20.00 U.S.at a time to avoid the hassle of paying each time.
