the 401 will split into hwy 20 and 40. 20, which goes along the south of Montreal, and is sort of like #8 is through stoney creek area. 40 goes along the top of the city and is like the QEW. from my experience, it is always jammed, all day ...(I go to Montreal 10-15x a year. Stay on 20 to get downtown. are you staying downtown ? if so, park at your hotel, the metro stops right at the Bell Centre., there are plenty of signs for the bell centre , if you want to park near it, it depends on how much you want to pay, there is plenty of parking, though you will have shop around for a good price. hope this helps a little. have a great time!!!
