Interstate 99

Interstate 99 is part of the US Interstate highway system. Its southern terminus is at Wolfsburg, Pennsylvania[?] at Interstate 76 (the Pennsylvania Turnpike) and its northern terminus (as of 2002) is at Bald Eagle, Pennsylvania[?] at United States Highway 220[?]. Eventually, the Pennyslvania and New York transportation departments plan to extend the interstate to Painted Post, New York at Interstate 86.

Notes Located east of Interstate 79 and west of Interstate 81, Interstate 99 is the bane of many road enthusiasts who treasure an orderly and sequential numbering system for Interstate highways. Interstate 99 is also known as the Appalachian Thruway and the Bud Shuster Byway, and it is the first Interstate highway to have its designation written into law (by Congressman Bud Shuster[?] in the National Highway Designation Act of 1995). Several other Interstates (including future Interstate 66 in Kentucky and Interstate 86 in New York) have since had their designations written into law.

The number 99 violates the standard numbering convention associated with Interstate highways. According to numbering guidelines, the lowest odd numbers are on the West Coast and the highest numbers are on the East Coast. Several north-south routes, including Interstates 81, 83, 87, 89, 91, 93, 95, and 97, all lie east of Interstate 99.
