The End of Rail

The RTA failed in Dane county, we can finally stop talking about commuter rail.  I had a thought related to this while sitting on the Beltline between Park and John Nolen where the road is essentially 10 lanes wide, how wide can we make this road?  The reality here is that we don't have enough land to widen roads and we have too many people driving into Madison.  Can't possibly talk about commuter rail or buses, so warm up the bulldozers and lets build us a road or 2 or 3.
