Future I-99(N-S)/US 220(N-S) Duplex
I-99 and US 220 form a 52 mile duplex from north of Bedford to south of Bald Eagle in Bedford and Blair Counties. The duplex will be extended to Williamsport, ultimately resulting in a 135 mile multiplex, surpassing I-70/I-76's record multiplex length in PA of 89 miles by 50%. This page covers the current US 220 (Future I-99) corridor from I-80 east to US 15.
Here US 220 has exited from I-80 at Exit 178, the eastern split of I-80/US 220 (I-80/Future I-99/US 220). US 220 makes a left turn onto its two-lane mainline roadway here, passing back under I-80.
From I-80 to the US 220 expressway to the north, there is only one intersection along this two-lane road. This is where US 220 meets Belle Springs Road.
Three miles from I-80, US 220 becomes an expressway. The first exit is for PA 477 near Salona.
The PA 477 interchange. Here we are still on the two-lane road, and the offramp leads to PA 477. The interchange is a diamond interchange with one cloverleaf.
Between the offramp and onramp, US 220 widens to a four-lane interstate-grade expressway.
The expressway is a bypass to Mill Hall and Lock Haven, both of which PA 150 passes through. PA 150 is a pre-expressway alignment of US 220. Much of the US 220 expressway guide signs have unnumbered exits. US 220 was supposed to become an extension of I-180, and so the exits along both US 220 west of Williamsport and I-180 east and south of Williamsport were unnumbered until 2001. I-180 has been numbered as a north-south interstate (but is signed east-west), and US 220 remains unnumbered for now, though eventually this expressway will become part of I-99 with numbered exits.
The PA 150 interchange is a trumpet interchange. PA 150 is a quarter mile to the north, and a connecting road extends from there to make this interchange. The US 220 exit sign on the left is quite an error, implying that US 220 exits its freeway.
The supposed US 220 exit is actually the PA 120 exit. PA 120 was once US 120.
At the interchange, the guide signs are correct. PA 120 ends at this partial diamond interchange.
The next exit along US 220 northbound is for Woolrich Road, which serves the McElhattan area.
The next exit is US 220's third meeting of PA 150. US 220 is signed concurrently with PA 150 along the US 220/PA 150 duplex near Milesburg. Then this US 220 expressway meets PA 150 at Mill Hall and again here at PA 150's end near Avis.
US 220 next meets up with PA 44 and forms a wrong-way duplex as a bypass to Jersey Shore. The duplex is covered on the US 220/PA 44 page.
Past the Jersey Shore bypass, US 220 narrows to two lanes near PA 287's southern terminus. There were plans to bypass US 220 with a new expressway alignment, the Susquehanna Beltway project, but these were deferred in 2004 to an unknown later date.
PA 287 meets US 220 at a traffic signal. The first traffic signal to the south along US 220 is in Port Matilda, some 60 miles to the southwest.
US 220 is a two-lane road for less than a mile. US 220 becomes a four-lane divided highway from near PA 287 to the western end of the Williamsport bypass.
Fourth Street is the old alignment of US 220 before I-180 and the southern Williamsport bypass were built.
The Fourth Street interchange is a partial interchange, allowing only northbound-northbound and southbound-southbound access. Williamsport Area High School get its own sign at this exit. US 220 becomes an expressway here, the Williamsport bypass.
The Reach Road interchange, a full diamond interchange, is next.
Reach Road provides access to the southern parts of western Williamsport.
The next interchange is for US 15. This interchange, once revamped into an expressway-to-expressway interchange, will be the northern split of I-99/US 220 and the southern split of I-99/US 15, i.e., I-99 will leave US 220 and join US 15. US 220 continues along US 15 southbound and I-180 eastbound, the latter just beginning at the same interchange. See the I-180/US 15/US 220 page.
