Traffic sucks on I-70 most of the day. It really sucks going westbound in the morning and eastbound in the afternoon. The elevated portion of I-70 is too narrow and can't be readily expanded. So what is YOUR solution to this problem? Putting in 8 lanes each way at ground level? The land acquisition costs would be prohibitive and there would be even greater negative impacts on the working class neighborhoods N of I-70.

One alternative would simply be to add another six lanes on top of the existing elevated I-70 with the top deck going east and the bottom deck going west, provided that the existing supports could withstand the extra loads.
