Starting July 21 the Highbury Road exit on 401 West (the Flying J exit ) will close for 6 weeks . I hate that . If I was headed back to the U.S. empty in the late afternoon I'd take my 10 hours at the Flying J and cross the border without delay at 3 a.m. and run all the way across I-94 doing the speed limit all the way to I-75 . I suppose there's a way to take another exit and wind around to the J . They also have the westbound exit on 400 for the Wyoming fuel stop closed . Then when you get to MI you can't get to the Marathon and Mobil (at the 262 ? )
