Interstate
95: I-99 in the state of Pennsylvania presently runs 51 miles
concurrent with U.S. Route 220. I-99 begins at its southern terminus, an
indirect connection (Route 220) with the Pennsylvania Turnpike at exit
146 (Interstate 70 and Interstate 76) near Bedford, Pennsylvania and
travels north past the city of Altoona to its current terminus near
Spring Mount in Blair County, PA. This northern terminus happens at
Pennsylvania Route 350. There I-99 reverts back to U.S. Route 220.
Plans for the near future will extend I-99 northeast past State College
(U.S. Route 322) to an interchange with Interstate 80 near Bellefonte,
PA. Additional future planning calls for the southern expansion of I-99
along the path of U.S. Route 220 over the Pennsylvania – Maryland border
where it will interchange with Interstate 68.
Long term discussions have speculated that the concurrency of I-80 and
US 220 and the completion of I-99 through to I-80 could eventually lead
to construction of an I-99 concurrency or another I-80 spur on or near
U.S. Route 15 toward New York State, with potential connections to I-90
and I-81 that would feed the Binghamton and Rochester New York areas.
The number designation of "99" (I-99) violates the AASHTO numbering
convention associated with the Interstate Highway System. However, in
1995, Bud Shuster, then-chair of the U.S. House Committee on
Transportation and Infrastructure and the representative of the district
through which the highway runs, sponsored a Bill (The National Highway
Designation Act of 1995) that so named the roadway “Interstate Route
I-99”.
The name given to I-99 locally is the Bud Shuster Highway. It is better
known as the Appalachian Thruway, the name that continues north with US
220 and US 15. |
