Your take on this project
Latest public update
CDOT's preferred alternative adds one managed express lane in each direction and rebuilds eight deteriorating bridges; the current estimate is ≈ $725M (earlier coverage cited ≈ $800M).
Open questions for the state ANALYSIS
- How will the ≈ $725M be financed — and what share comes from tolling?
- What happens to cost and scope if the record of decision slips past 2027?

Spend-to-date: not published. Colorado does not publish what it has spent on this project, so this field is left blank rather than estimated. It will fill from TOPS/CORE vendor expenditure data as payments are matched to projects.

Both endpoints are drawn from the source records below; the change, percentage, and average are our arithmetic (CALC). The average covers the 5 of 50 tracked projects with two published estimates — for the rest, the state has published a single figure, so their drift is unknowable, not zero. Estimates move in both directions — we show the honest record either way.

The money is published; the names are held. Each row below carries the contract value, what has been paid to date so far as it is published, and our confidence grade — the same figures as always, from the same official records. What is withheld is the vendor's name, the record link that names it, and the campaign-finance search that sat beside it. That is a deliberate decision taken pending legal review, not a figure we could not find: a blank cell would have said the opposite. What WITHHELD means
