I-70 can't continue as is. It needs a rebuild and ideas on relocating I-70 through Denver aren't realistic. I-76 and I-270 aren't designed to handle half the traffic of I-70. They would need 3-4 more lanes in each direction and the environmental concerns with it aren't even discussed.

Clear Creek runs parralel to 76 and Sand Creek runs parralel to 270, while 270 crosses the Platte the same as I-70. Considering the refineries and the water treatment plant are there, is it best to create a toxic zone?

In my opinion, Globeville will be swallowed up by Denver properties expanding that direction anyway. The relocation and construction of a boulevard would be much more costly than the plan in place.
