Can Minnesota afford the upkeep of roads and bridges? Broadcast: Midday, 08/10/2007, 11:00 a.m. With the wreckage of the I-35W bridge still slumped in the Mississippi River, options for rebuilding are beginning to surface. State and federal government now must deal with questions about the eroding state of our bridges and highways and how we pay for the upkeep of our infrastructure. Guest: Tim Penny: senior fellow, Center for the Study of Politics and Governance at the Hubert H. Humphrey Institute of Public Affairs.
