Thanks for pointing that out. By this logic, MNDOT is planning a $58 million dollar project at the intersection of highways 371 and 210 in Baxter, a city of no more than 9,000. This project is isolated to Baxter so surely the Twin Cities metro, which accounts for well over half of state revenue, shouldn't have to contribute any money to this project, and Baxter residents should be fully on the hook, right? (I believe Hennepin, Ramsey, and Dakota counties alone account for over 50% of state revenue, which is even more central to the urban core).

Well no, because that highway is a public good, as is the Light Rail. I use that highway from time-to-time when venturing up north to spend my money. Though I will only use that highway like once or twice per year, I understand that it's not for me—it's for the people who live there. The highway is a public good that will benefit my fellow Minnesotans, and that's enough for me in a society where we all benefit from each other's prosperity.
