If you can take the light rail, you can take 35W. The bridge was on the north end of town, so traffic can move from the south into MPLS.
The light rail is fine. I take it for all events. Some convienent spots to get on are Fort Snelling (Highway 5 and 55 intersection) and Mall of America.
It costs $3 (if memory serves me). There are a few bars along the way, but you would technically have to pay each time you stop. I think there is a event pass that is good for 6 hours or something that might work. The stops w/ bars that are near Minnehaha Pkwy right after the VA hospital, then Caboose/Whiskey Junction. It is near a bunch of bars in downtown MPLS too.
You might end up taking it for all events just to avoid the traffic/parking headaches. Unless you want to tailgate, it is perfect for sporting events/concerts.
