History

In the 19th century, the road that would eventually become US 220 between Hollidaysburg and Bedford was a turnpike, appropriately called the Hollidaysburg and Bedford Turnpike, chartered in 1835. Unlike its successors, this highway veered east to Hollidaysburg along modern-day PA 36. The highway was still referred to as such as late as 1866. Today, this highway is William Penn Road, the Dunnings Highway, and a section of Special routes of U.S. Route 220, US 220 BUS in Bedford. US 220 was proposed in 1926, along with the rest of the National Highway System. At its inception, the highway south of Bedford followed its current path, but it branched off of the modern highway, using US 220 BUS through Bedford. North of here, the highway closely paralled its modern counterpart, following the old Hollidaysburg and Bedford Turnpike. It picked up a concurrency with US 22 at Duncansville, Pennsylvania, Duncansville headed east to Hollidaysburg, then followed modern-day PA 36 north to a junction with Plank Road, and then followed US 220 BUS through Altoona. It then passed through the Tuckahoe Valley northeasterly, paralleling the modern freeway to the northwest and servicing Tyrone directly. From Port Matilda, the highway has since become US 220 Alt. to Milesburg, Pennsylvania, Milesburg. It then passed south along Pennsylvania Route 144, PA 144 to service Bellefonte, and thence along PA 550 and PA 64 to Mill Hall. From here to just outside Avis, the highway is signed PA 150. As PA 150 turns to service the expressway, US 220 continued on to service Jersey Shore directly. At a junction with modern-day PA 44, the highway swung north on that highway. For a few miles, the highway from here has changed little from its original incarnation. It then left the expressway's alignment via Quadrant Route 2014, and left Williamsport north via the Susquehanna Trail, now an old alignment of US 15, and terminated at the New York line at Lawrenceville, Pennsylvania, Lawrenceville. Before the adoption of the highway system in the state, Pennsylvania's highway department petitioned for a redrawing of the highway map through their state to keep each number fully concurrent with existing auto trails. As a result, US 111 was extended over the intended alignment of US 220, and the highway was rerouted to its modern alignment north of Williamsport. Through Williamsport, the highway followed 4th Street, Campbell Street, Park Avenue, Hepburn Street, 7th Street, Market Street, and Washington Street, now Washington Boulevard. Out of Williamsport, the highway is Quadrant Route 2014 to Muncy, then PA 405 to its modern alignment. As a result of this realignment, US 120, US 111, and US 220 bore a concurrency through Williamsport. Through and north of Athens, the route has been superseded by PA 199 In 1927, Pennsylvania dramatically expanded its own state highway system, and assigned numbers to US highways without existing numbers. PA 64 was assigned to the route south of Bellefonte and PA 44 from there to Mill Hall (which at the time extended to McConnellsburg, Pennsylvania, McConnellsburg). From Hughesville north, the highway was signed as a northern extension of PA 42 to the New York line. These designations were deleted the year after. Few major changes occurred in the highway before the construction of the Bud Shuster Highway. The highway's alignment through Williamsport changed several times before the town was fully bypassed. In 1941, it shifted to its current alignment north of Muncy, in addition to modern-day SR 2036. 1946 saw the swapping of PA 64 and US 220, fully following modern-day US 220 Alt and PA 150. In 1964, PA 36 swapped alignments with US 220 south of Altoona, which now followed Plank Road, bypassing Hollidaysburg. In the late 1960s the federal government planned a dam in the Bald Eagle Valley, which would flood most of the original alignment through Howard. It was at this time when US 220 was realigned to break away from the original alignment just before Milesburg, pass to the north of Bald Eagle State Park and reunite with its former alignment about 1 mile east of Beech Creek. The old alignment still exists in sections, and is used for access to the reservoir.


Freeway alignments

The first sections of a freeway alignment of US 220 were begun in the mid-1960s with the construction of I-80 through the state. The first section of freeway solely dedicated to US 220 was opened in 1967 from Avis to Jersey Shore. The next few years saw the rapid development of an expressway/freeway along the US 220 corridor, including the completion of the Bedford Bypass in 1970, and the final section of expressway north of I-80 completed in 1978. The expressway from south of Athens to the New York State Route 17, Southern Tier Expressway was completed in 1974. 1996 saw the adoption of the designation I-99 between Bedford and I-80.


Future

PennDOT plans to upgrade the interchange with Interstate 80 in Bellefonte to a high-speed Interchange (road)#Semi-directional T interchange, expressway-grade interchange, bringing I-99 to Interstate Highway standards, Interstate Highway Standards. The project is expected to start in 2022, following the completion of a related project for a local I-80 interchange with PA 26.
