Pennsylvania Roads - US 15/Future I-99 - Williamsport-Tioga

US 15 and Future I-99, Williamsport to Tioga



US 15 northbound in South Williamsport, where the NB and SB roadways form a one-way pair.


After US 15 SB exits I-180 (immediately to the right), it then must turn off of itself to go over the Susquehanna River bridge in the background. Courtesy Doug Kerr.


On 3rd St. eastbound, east of where US 15 crossed the Susquehanna River. Construction dictates that traffic heading west on I-180 (with its associated routes) head east along the route that normally only carries traffic heading southeast on I-180 (or northeast on US 220) from 15 north. It also dictates one ugly ex-US 22 shield.


All are courtesy Doug Kerr on US 15 SB. In the first photo, there should be a "NEXT RIGHT" on the US 220 SOUTH BGS; one thing old signs are bad at is telling you which lanes they specify. The third photo is getting really close to US 220 if it hasn't merged already. I-180 begins at the US 15/US 220 interchange. It once was a N-S route, which meant that although it was a proper multiplex, though brief, with US 15, it had a considerable wrong-way plex with US 220. Now 180's been turned 90 degrees, although exit numbering hasn't changed, so it's one of the only highways whose numbers decrease heading eastbound. US 15 and US 220 still share this brief wrong-way multiplex, of course.


NB leaving I-180/US 220.


These are either at or on SR 1011 (the last two are on NB 1011), which is old US 15 north of Williamsport and crosses the freeway alignment at least twice. It's conceivable the shields on PA 642 WB date from the opening of the US 15 freeway segment through here. The I-80 trailblazers are somewhat misleading, as the only decent way down is to go back through Williamsport, either following US 15 or I-180 several miles southward to get to I-80.


NB past some of the most beautiful mountain scenery in Pennsylvania to some of the last construction on US 15. The PA 184 interchange is one of the last steps to completing US 15 to Interstate standards so that I-99 can be brought up this way to New York. The left turn is the existing at-grade intersection to be removed.


More views of beautiful scenery from old US 15 just under the freeway, Lycoming Creek Rd., up to the beginning of PA 14.


After leaving PA 184, the northbound roadway is getting reconstructed up to PA 284 (route numbers are grouped in PA by last two digits) from the original twisty two-lane to something with shoulders and flatter curves.
