Notes
This road was originally a "line on a map" Interstate. For many years, it existed so more people can have a path through the Appalachians than to relieve congestion on that busy Roanoke-Harrisburg route.
However, I-81 has become a major route for interstate truck transportation in recent years. Trucking companies that have tired of fighting big-city congestion along Interstate 95 are now opting to use this less congested inland route. Virginia has decided to widen its entire portion of I-81 to a minimum of four lanes in each direction to accommodate increased truck traffic. The new Virginia I-81 would completely separate car and truck traffic. [1] (http://virginiadot.org/infoservice/news/newsrelease.asp?ID=CO-010)
I-81 runs together with Interstate 77 in Wytheville, Virginia for about 10 miles (16 km), but the two go in opposite directions, creating a wrong-way multiplex. Motorists traveling northbound on I-81 are also traveling southbound on I-77, though they are actually going east. Likewise, motorists traveling southbound on I-81 are also traveling northbound on I-77, though they are actually going west.
I-481 around Syracuse, New York was originally called I-281.
There was an eastern branch, called I-81E, that was a spur from Scranton to Pocono in Pennsylvania. That highway is now I-380.
At I-81's northern terminus, a toll bridge over the St. Lawrence River connects it to the MacDonald-Cartier Freeway (ON Provincial Route 401) in Ontario.
