Disruption to Metro Transit bus service has been minimal so far, spokesman John Siqveland said. One express route, No. 652 running between Minnetonka and the University of Minnesota in Minneapolis, is being diverted from its usual path through the tunnel and onto downtown surface streets, Siqveland said.Okay, route 652—and? Well, looking at Metro Transit's interactive map, it turns out that 652 is the only bus route that goes through the tunnel—and it only has two inbound runs in the morning and two outbounds in the evening.
Admittedly the route is an express to the University of Minnesota, so it's running at reduced frequency during the summer, but it's galling to think that so little effort has been expended to balance mode share through the most significant freeway bottleneck in the Twin Cities.
There were 164,000 vehicles using the tunnel each day in 2007, so even if the buses were pretty full, four per day probably only represents a total mode share of 0.05%. I hope things are a bit better during the regular UMN school season, but clearly the share of transit users would still be tiny: It'd take 15–20 times as many buses to reach just 1%.
