Great Circle Route
I-84 East to I-80 East Take I-76 East (the Pennsylvania Turnpike) to Exit 29 Follow the signs to Pittsburgh.
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.
The distance considered for the journey is the shortest route chosen between the places. Also traffic rules like one ways and no entries have not been considered.the road distance between the above places is 215 miles / 346 km
The road distance between the above places is 2530 miles . This is the distance when the shortest route is chosen. Traffic rules like ‘No Entries’ and ‘One Ways’ have not been considered when calculating this distance.
If you mean by the words "direct route" the shortest distance between two places, distances between two places are shortest at the equator, because of the shape of the planet. If you mean which direction should be traveled to minimize distance, the route taken should be as straight a line as possible.
Because that location is the lowest, shortest route between oceans.

The shortest route is on I-90 W.
