Work crews are inspecting the Leo Frigo bridge in Green Bay this week, but it’s just part of a larger maintenance cycle for Wisconsin’s bridges. Work crews inspect every bridge in the state, large or small, every two years. DOT Spokesman Mark Kantola says that for small bridges that don’t need big closures, you might see flagging operations or lane shifts. Many problems can be spotted and repaired on site before they turn into larger issues. Kantola says larger repairs and rebuilds have to come through state projects.
