the shortest air route is a great circle
Assuming you're driving (and not flying) the shortest route is 86 miles.

The shortest route between two points on the surface of a planet, when routes are limited to the planet's surface, is the arc of the great circle that connects the two points. The shortest route between two points anywhere, without regard to intervening matter or energy preventing the route from being followed, is always the line connecting the two points.
Great Circle Route
The fastest shortest path algorithm for finding the most efficient route between two points is Dijkstra's algorithm.
Take I-94 WEST from Milwaukee to I-494 SOUTH at EXIT 249 in Minnesota outside of St. Paul.Take I-494 SOUTH to South St. Paul.

Because that location is the lowest, shortest route between oceans.
The shortest route is on I-90 W.
We are an aircraft delivery company and have often reviewed the shortest flying route to Hawaii. The shortest direct route between two airports is Monterey, California to Hilo Hawaii at 2012 Nautical Miles. Fred Sorenson Flight Contract Services, Inc.
