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

I-80 and US 220 join for 17 miles from Exit 161 near Bellefonte to Exit 178 east of Mackeyville in Centre and Clinton Counties.

Westbound on I-80/Alternate US 220 (which was I-80/US 220 before November 2002) one month before the US 220 relocation. A month after this photo was taken, US 220 was moved from this freeway section to that on PA 26, but since the relocation had not yet taken place, the US 220 number is covered up. In November 2002, the cover was removed. This exit marks the new western split of I-80/US 220.

12 miles to the east, an old alignment of US 220 enters the picture. PA 64 was US 220's routing before US 220 was relocated onto current PA 150. A second relocation moved US 220 to I-80.

Timothy Reichard 8/3/02

The I-80/US 220 bridges over PA 64 were rebuilt in 2001, and PA 64 was reconstructed in the area of the interchange.

Reassurance shields, including an undersized direction banners, are posted just past the PA 64 interchange.

Another 5 miles to the east, signs for the eastern split appear.

Seventeen miles from the western split, US 220 leaves I-80 and heads toward Lock Haven and Williamsport. The interchange is a simple diamond interchange.

The offramp is US 220 north, which turns left onto a two-lane road almost free of intersections (there is only one intersection between this interchange and the Susquehanna Beltway [US 220/Future I-99] expressway to the north). The road heading to the right meets two gas stations and then continues as an unpaved road

Turning north onto US 220, signs for the westbound duplex stand here. The median of I-80/US 220 is fairly wide here.

Timothy Reichard 8/3/02

From the other direction, US 220 south meets I-80.

Cities without mileages are posted near the interchange.

Timothy Reichard 10/14/02

Westbound on I-80, traffic bound for US 220 south should remain on I-80 for the next 17 miles.

Timothy Reichard 10/14/02

Westbound on I-80 at the US 220 north exit. The I-80/US 220 duplex begins here.

Reassurance shields near the eastern split.

Nearing the new western split. US 220 was relocated onto PA 26 when the Future I-99 freeway was completed and opened in November 2002. This photo was taken a month before the relocation, but signs had begun to change. The US 220 shields was later uncovered.

The new western split of the three-miles-shorter I-80/US 220 duplex. US 220 exits to follow the new US 220/PA 26 freeway duplex on the Bellefonte bypass, previously PA 26 alone. The western three miles of the old duplex are now I-80/Alternate US 220, with the new alternate route replacing the old US 220 from here to the US 322 interchange north of Port Matilda. See the I-80/Old US 220 and I-80/Alternate US 220 pages for more coverage.

Timothy Reichard 10/14/02

Northbound on the new US 220/PA 26 duplex, formerly PA 26 alone, nearing I-80. Here US 220 splits from PA 26 to follow I-80 east, while Alternate US 220 begins southbound following I-80 west. The JCT sign for US 220 should be changed. These are more October 2002 signs, from a month before the US 220 relocation and Alternate US 220 commissioning.

I-80(E-W)/Future I-99(N-S)/US 220(N-S)/PA 26(N-S) Quadruplex
I-80(E-W)/Future I-99(N-S)/US 220(N-S) Triplex

The I-99 designation will someday join the truncated I-80/US 220 duplex from Exit 161 east of Milesburg to Exit 178 east of Mackeyville. Interchanges at Exit 161 and Exit 178 will be reconstructed as high speed interchanges, replacing the current diamond-type interchanges. Additionally, a new interchange Exit 163 will be built for PA 26 and its local traffic, thus making a two-mile-long I-80/I-99/US 220/PA 26 quadruplex.
