The Minnesota Vikings professional football (American football) team has honed in on a site in Arden Hills, MN. You can read about the agreement with Ramsey County in the Star Tribune here (you can also hunt around the newspaper and other news sources for opinion pieces). I'm very curious to see the traffic study that gets done for this (Mr. Wilf – we're available if you'd like our help with the traffic study).
Below is a map that shows the location. At first blush, the site appears to have very good freeway access from Interstates 35W and 694. But if you look a little closer there are significant limitations for anyone trying to get to the site from the south or west (i.e. the majority of the fans). Everyone from those directions will be forced to use the I-35W/Co Rd 96 interchange to get to the game.
I hope they can get an off ramp built at Co Rd H, but that interchange doesn't have that move now because of the difficult weaving areas that are caused by Highway 10 and the close proximity to Highway 96. I haven't looked into it enough to know if that's even feasible, but I assume Mn/DOT has.
Below is a scan of the conceptual site plan from my morning paper (I haven't been able to find this anywhere online – guess that's why I still get an old fashioned hard copy). According to the team's website, the site will have about 21,000 parking stalls.
One inbound lane can bring in about 2,000 vehicles per hour if the lane is unimpeded and traffic is rolling at a good clip (so we're being generous with this number, but it's a round number to use). So, if we're trying to get the 21,000 fans into the site in a very chaotic 2 hours before kickoff, we better have 6 lanes of traffic rolling into the site. The plan below is very conceptual, but I don't see that kind of access being provided.
I hope the Vikings get a traffic engineer involved pretty soon with the site planning. Unlike the current Metrodome site, there's no Light Rail Transit line to feed in the fans or the existing parking ramps available throughout downtown Minneapolis. Since the site is a blank slate, the Vikings need to create all of the infrastructure to make this work. At least there isn't much conflicting traffic for fans to contend with on a Sunday morning.
