Interstate 86 (I-86) is an Interstate Highway that extends for 207 miles (333 km) through northwestern Pennsylvania and southern New York in the United States. The highway currently exists in two segments: the longer of the two begins at an interchange with I-90 east of Erie, Pennsylvania, and ends at the Chemung-Tioga County line, while the second extends from I-81 east of Binghamton to NY 79 in Windsor. When projects to upgrade the existing NY 17 to Interstate Highway standards are completed, I-86 will extend from I-90 near Erie to the New York State Thruway (I-87) in Woodbury. The current and future alignment of I-86 is known as the Southern Tier Expressway west of I-81 in Binghamton and the Quickway east of I-81.
I-86 currently travels 6.99 miles (11.25 km) in Pennsylvania and 199.86 miles (321.64 km) in New York. Except for a section of about 1.5 miles (2.4 km) that dips into Pennsylvania near the New York village of Waverly and the Pennsylvania borough of South Waverly, the rest of I-86 will be in New York. The section of NY 17 through South Waverly is maintained by the New York State Department of Transportation (NYSDOT), however. The Southern Tier Expressway section of I-86 and NY 17 comprises Corridor T of the Appalachian Development Highway System. I-86 connects to U.S. Route 219 (US 219) in Salamanca, I-390 near Avoca and I-99 / US 15 just west of Corning.

Interstate 84 (I-84) is an Interstate Highway with two non-contiguous sections. This eastern section extends from Dunmore, Pennsylvania (near Scranton) at an interchange with Interstate 81 east to Sturbridge, Massachusetts, at an interchange with the Massachusetts Turnpike (Interstate 90). I-84 has mile-log junction numbering in Pennsylvania; otherwise, exit numbers are roughly sequential. Another highway named I-84 is located in the northwestern United States.
Interstate 84 starts in Pennsylvania at Interstate 81 in Dunmore, Pennsylvania, a suburb east of Scranton. After two miles (3 km), I-84 interchanges with Interstate 380, with I-380 going southeast through the Poconos and I-84 continuing almost due east into Wayne and Pike counties. The Pennsylvania section is the only segment of I-84 that uses mile-based exit numbers; it began replacing sequential numbers in 2001.
This section of Pennsylvania is very lightly populated, and there are no major settlements on or near I-84, although it offers access to popular outdoor recreation areas such as Lake Wallenpaupack and Promised Land State Park. Its right-of-way is very wide, with a large median strip between the two roadways as it passes through densely wooded country, except for the swampy areas in southern Wayne County. The only development along Pennsylvania's section of I-84 is where US 6 and 209 start to parallel closely and form a commercial strip just south of Matamoras, just west of the Delaware River. I-84 reaches its highest elevation in Pennsylvania and in the east just west of exit 8 at 1800 feet.
Interstate 84 (I-84) in Massachusetts is the eastern-most segment of the eastern I-84 highway originating in Dunmore, Pennsylvania, (near Scranton). Within Massachusetts, I-84 exists in the towns of Holland and Sturbridge. Known as the Wilbur Cross Highway, it has also been signed as Massachusetts Route 15 between 1948 and 1980 as well as Interstate 86 between 1971 and 1984.
The highway originated as Route 15, an extension of Connecticut Route 15 (then known as the Wilbur Cross Parkway). The extension started in Holland, and within 1⁄4 mile (0.40 km), it entered Sturbridge as Mashapuag Road. It then followed Union Road to Sturbridge Center ending at Route 131.
Between 1949 and 1952, the Massachusetts Department of Public Works (MassDPW) initiated construction of the Wilbur Cross Highway extension to US 20 in Sturbridge, with two lanes in each direction separated by a wide median and frequent U-turns.
