interchanges near Lehighton (Mahoning Valley), Albrightsville (Route 903), and White Haven (Pocono), and Interstate 81, which serves as an alternate route for the much busier Interstate 87 and Interstate 95, particularly for travelers from Toronto, Syracuse, Binghamton and Montreal to Philadelphia, Baltimore, and Washington, D.C. Other interstates that serve the region are Interstate 84, which begins in Scranton and goes east to New England, and Interstate 78, by way of Route 33 or Route 309. Restoration of passenger rail service NJ Transit is rebuilding trackage on the Lackawanna Cut-Off route from Scranton through the Poconos to Hoboken, New Jersey. There is no estimated target year when the Lackawanna Cut-Off Restoration Project will be completed to the Poconos. The service would consist of nine trains per day in each direction. The NJ Transit board approved in April 2022 a $32.5 million contract for improving a tunnel and restoring track to part of the line between Blairstown, New Jersey and Port Morris Junction, New Jersey, a segment in which trackage had been removed in the 1980s. Until 1970, the Erie Lackawanna Railway operated long-distance trains through the Poconos to Buffalo and Chicago to the west, and Hoboken to the east, the last train being the Lake Cities. Air travel There are two airports that are located just outside the region: the Wilkes-Barre/Scranton International Airport and the Lehigh Valley International Airport. Geography The Pocono Mountains is a defined area encompassing portions of Carbon, Monroe, Pike, and southern Wayne Counties in Pennsylvania. In total, the Poconos encompasses over . Some definitions also extend the Poconos to Lackawanna, Luzerne, eastern Schuylkill, and Susquehanna Counties. The Poconos are geologically part of the Allegheny Plateau, like the nearby Catskills. The Poconos' highest summit, Kistler Ledge in Monroe County, reaches over , while its lowest elevation is in Pike County. The Delaware River flows through the Pocono Mountains and gives the region its name, from a Native American term roughly translating to "stream between two mountains". The Lehigh and Lackawaxen Rivers also flow through the region, totaling about 170 miles (270 km) of waterways. Climate Glaciated Low Plateau Region According to the Trewartha climate classification system, the Glaciated Low Plateau region of the northern and eastern Poconos has a Temperate Continental climate (Dc) with warm summers (b), cold winters (o) and year-around precipitation (Dcbo). Dcbo climates are characterized by at least one month having an average mean temperature
