I-81 was originally a "line on a map" Interstate. For many years, it existed more to provide a path through the Appalachians than to relieve congestion on any specific route. The Appalachian Mountains are a system of North American mountains running from Newfoundland and Labrador, Canada to Alabama in the United States, although the northernmost mainland portion ends at the Gaspe Peninsula of Quebec. ...

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. Map Interstate 95 (abbreviated I-95) is an Interstate Highway that runs 1,927 miles (3,101 kilometers) north-south along the east coast of the United States. ...

Notes

I-81 looking southbound near milepost 245, Harrisonburg, Virginia.

• Virginia has proposed to widen its entire portion of I-81 to a minimum of three or four lanes in each direction to accommodate increased truck traffic and to toll non-passenger vehicles. Some sections of the new Virginia I-81 may completely separate car and truck traffic. For more comprehensive information on Virginia's plans for the I-81 corridor, see this site. A similar propsal in Pennsylvania has also been studied.[1]

• 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 concurrency. 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.

• There was an eastern branch, called I-81E, that was a spur from Scranton to Pocono in Pennsylvania. That highway is now I-380.

• I-481 around Syracuse, New York was planned as I-281, and the first portion of the bypass to be completed was briefly signed as I-281. However, the route number was changed to avoid confusion with nearby NY 281.

• Around I-81's northern terminus at the Canadian border, two toll bridges over the St. Lawrence River connect it to unsigned Ontario Highway 137, a short link to Highway 401 in Ontario. The bridges are on opposite sides of the border (southern bridge is I-81, northern bridge is ON 137). The southern bridge is one of the few remaining 2-lane Interstate stretches left on the system. The border itself is marked by a 90-foot bridge across International Rift between Wellesley Island, New York and Hill Island, Ontario. 38 miles to the east lies Highway 416 leading to Ottawa.

• I-81 parallels U.S. Route 11 for most of its path.

• I-81 connects indirectly with I-76 PA Turnpike in Carlisle, PA (Carlisle Interchange) in order to connect you need to go 1 mile on US Route 11. Dubbed by locals as the "Miracle Mile".

• Another way to I-76 PA Turnpike it connects for thoses of you who prefer interstate is via I-83 to I-283 (Harrisburg East Interchange).
