United States Alternate Route 220 and Pennsylvania Route 504 join for 4 miles from Unionville to Wingate in Centre County.

Heading westward on Alternate US 220 south/PA 144 north in Wingate. PA 144 splits off to the north to tease I-80 on its way to Snow Shoe. The Alternate US 220/PA 504 duplex and PA 504 itself begin straight ahead.

Reassurance shields westbound along the duplex. Before November 2002, neither Alternate US 220 nor PA 504 were designated along this stretch of road. Instead, the road was US 220. In November 2002, new US 220/Future I-99 opened to the east, and US 220 was relocated to the new freeway. Old US 220 became Alternate US 220 alone. Then in 2004, PA 504 was extended eastward from Unionville (its former end) to PA 144 in Wingate.

A few reassurance shields on Alternate US 220/PA 504 had not been updated with PA 504 shields by the end of 2004.

Other signs also had not been changed. This JCT PA 504 sign stands in Unionville along the duplex at PA 504's old end. The sign is now unnecessary.

PA 504 splits to the west in Unionville on its way to Black Moshannon State Park.

 

David Brunot 2004

Eastbound along PA 504 in Unionville after PA 504 was extended. The intersection ahead with Alternate US 220 was PA 504's end for decades. Even after the 2004 extension, an END sign remains posted here. PA 504 turns left ahead to join Alternate US 220 north.

 

David Brunot 2004

Now northbound on Alternate US 220 in Unionville. PA 504 used to begin to the left. Now the route continues northeastward for four miles with Alternate US 220.

 

David Brunot 2004

New reassurance shields northeastbound.

 

David Brunot 2004

A new END sign is posted for PA 504 at its end at the junction of PA 144. The Alternate US 220/PA 144 duplex begins ahead at the gas station.
