I-80(E-W)/Old US 220(N-S) Duplex

Interstate 80 and United States Route 220 used to join for 20 miles from Exit 158 near Milesburg to Exit 178 east of Mackeyville in Centre and Clinton Counties. US 220 was relocated upon completion of the Future I-99 expressway north of State College. The relocation truncated the duplex PA 150 at Exit 158 to PA 26 at Exit 161. Between those exits, Alternate US 220 takes US 220's place. The I-80/US 220 duplex remains unchanged to the east to Exit 178 for now, until I-99 and PA 26 are relocated onto I-80/US 220, making the state's fifth quadruplex, I-80/I-99/US 220/PA 26. Below are photos from the part of I-80/US 220 that is now I-80/Alternate US 220.

I-80 was announced on a big green sign at the Milesburg interchange of US 220/PA 144, PA 144/PA 150, and US 220/PA 150. The US 220/PA 144 duplex is now Alternate US 220/PA 144, and the US 220/PA 150 duplex is now Alternate US 220/PA 150.

Just past that interchange, the standard Traveler Info sign is posted along US 220/PA 150.

Halfway along the old US 220/PA 150 duplex, the northern split looms ahead and marks the western split of I-80/Alternate US 220, formerly I-80/US 220.

The old northern split of US 220/PA 150 and the old western split of I-80/US 220. PA 150 continues ahead to the north along US 220's former, pre-I-80 routing. Alternate US 220 joins the previous alignment of US 220.

Just past the overpasses, a left turn places one on a ramp to I-80 westbound.

On the other side of the interchange with I-80, and looking south, old US 220 southbound entered from a cloverleaf ramp just past the onramp to I-80 west..

On the south side of the overpasses, the two duplexes were signed.

A right turn leaves old US 220/PA 150 and joins I-80/old US 220.

Three miles to the east on I-80, the new-in-2002 western split is signed with PA 26. PA 26 is a two lane road to the north and a four-lane expressway to the south, which was constructed in anticipation of the new I-99 in the State College area. In October 2002, US 220 was rerouted onto that expressway, and US 220 now leaves the new US 220/PA 26 duplex to join a shorter I-80/US 220 duplex. Ultimately, I-99 will be signed on both duplexes, making them the I-80/I-99/US 220/PA 26, I-80/I-99/US 220, and I-99/US 220/PA 26 multiplexes.

For now, the PA 26 interchange is a modified diamond interchange. The interchange will be revamped to interstate standards by 2006.

The previous sign was replaced by this guide sign, which includes a covered-up US 220 shield.

PA 26 northbound, just north of where US 220 split to join I-80 east. At the same interchange, Alternate US 220 begins. This is the ramp to I-80/Alternate US 220.

Continuing east on I-80/US 220. The rest of the I-80/US 220 duplex remains unchanged for now. For more coverage of the unchanged I-80/US 220, see that page.

Reassurance shields for I-80/Alternate US 220 a month before the relocation. Alternate banners were added to all the US 220 shields on I-80 west of the PA 26 interchange.

 


Timothy Reichard 10/14/02

US 220 used to split from I-80 at Exit 158 to join PA 150. Now Alternate US 220 takes on this routing.
