Alternate US 220 was signed in November 2002 to take over the old
alignment of US 220. The US 220/Future I-99 was opened north of State
College, and US 220 was relocated to the new alignment, overlapping
parts of US 322 and PA 26 as well. Alternate US 220 now runs from
US 220/US 322 in Martha Furnace northeastward to I-80 and eastward
along I-80 to meet US 220/PA 26. The alternate route overlaps with
PA 144, PA
150, and I-80.

Just ahead, junction signs for I-80/Alternate US 220 are posted with
an old, now unnecesary, junction sign for US 220. Before the relocation,
US 220 followed I-80 where Alternate US 220 follows it today (west
from this interchange), and US 220 did not follow PA 26 as it does
today.

US 220 multiplex page.
