A project to cap four blocks of Interstate 670 in downtown Kansas City - from Wyandotte Street to Grand Boulevard - turning the highway into a tunnel and building a roughly 5.5-acre park on top, connecting downtown to the Crossroads Arts District. Total project cost has been reported between $217M (2024) and $315M (2026) as the scope and cost estimate evolved; this is exactly the kind of figure drift Scope is built to show rather than silently update.

This is a project where the funding stack itself is the story: two federal grant applications have not succeeded, a federal loan's status is unconfirmed in the most recent reporting, and the city is now weighing bonds to bridge the remaining gap on a project whose total cost estimate has grown by roughly $100M since 2024.
No litigation found in public reporting as of this preview.
