When the new crossing was built we had a similar problem. The Jersey barriers were too close together. Did $10,000 damage to our rig. I stopped the MH when I heard the first scrape but could not open the door as it hit the barrier. I sat there for a few minutes wondering what to do. A US border guy came over yelling at me to move. I refused. he gave me 2 options. Move the rig or just sit there. They will arrest me and get a tow truck to move the rig. I moved on. The lack of any signs is ridiculous. I sure hope someone solves this problem. You cannot take the downtown crossing .
