Roads. There's a large port nearby, but it doesn't depend on canals. The electrical grid is also maintained by the state along with the other states on the same regional grid, again, the federal contribution is largely limited to funding.
GPS, OK, that's useful and it's existence depend(-s/-ed?) on the federal government/military I guess.
Who makes it viable by protecting international shipping, guarding the coast and regulating port infrastructure? (If you’re on a Great Lake, it absolutely depends on canals. That and Canada.)

Not how North American grids work, outside Alaska, Texas, Florida and maybe the SPP. States have influence on NERC through the utilities. Grids don’t line up neatly with state lines, and the whole mess requires regular federal coordination.
