Agreed. There aren't many (if any) apples-to-apples comparisons of highway removal for a facility of this type. Denver is actually pretty lucky in not having many spurs and bypasses. We have a lot of one-way couplets that actually saved us from freeways.

You'd be replacing I-70 with a street that has twice the daily traffic of Colorado Boulevard- a street that Sachs has vilified for being an auto nightmare. Just what kind of tree-lined boulevard with meandering bicycle facilities will support 100,000 vehicles per day? It's called a surface highway.

From an urban design standpoint, it's most definitely possible to build a boulevard that processes that kind of ADT while still maintaining place and appropriate scale. Most examples come from Europe though. And I'm not sure it would apply to this area (not at least for several, several decades, if ever). But it's possible.

Yeah.

This, to me, is really one of CDOT's last big expansion project opportunities left in Denver proper (except central I-25 (maybe some more lids?!)). As the city continues to develop and the demographics change, it will get massively harder to implement roadway expansions.
