Business US 220(N-S)/PA 453(N-S) Duplex
Business US 220 and PA 453 join for a few blocks through Tyrone in Blair County.
PA 453 follows a zigzagging path through Tyrone. The route takes four turns to get through town. At this turn PA 453 turns onto Business US 220.
Just ahead, another PA 453 shield points to the south. The northern part of PA 453 is signed also as "TRUCK ROUTE", ending at this intersection.
Here is the view of the northern split along Business US 220 southbound.
A third view shows the start of the truck route portion of PA 453. This view is along Business US 220/PA 453 northbound.
Here is the duplex through Tyrone. The signs at the right read SOUTH PA 453 and TO I-99.
A few blocks ahead, PA 453 splits off to its new (as of 1976) four-lane alignment to meet the I-99/US 220 expressway.
Turning left onto PA 453, I-99/US 220 is well signed here.
Just head, overhead signs for US 220 appear, with I-99 shields along the side of the road. This is how most of I-99/US 220 is signed. The US 220 expressway from Bald Eagle to Bedford was originally a Tyrone bypass (US 220) and a Bedford bypass (also US 220). Those bypasses were opened in the 1970s, but the I-99 designation was not assigned until the bypasses were connected in the mid-1990s. US 220 overhead big green signs with I-99 shields along the side of the road are common.
Heading back to town along PA 453 northbound, PA 453 turns right here from the four-lane highway to the two-lane street that is Business US 220. You may have noticed that not a single Business US 220 sign has appeared in any of these photos! In fact, Tyrone does not have any Business US 220 shields anywhere. Business US 220 is signed at its northern terminus north of town. If you begin on Business US 220 there and follow the business route southward, the first Business US 220 shield appears at the Tipton exit of I-997 miles to the south! I-99 is known to be poorly and cheaply signed in the regionBusiness US 220 is even worse with its lack of signs.
Before the US 220 Tyrone bypass was completed in the 1970s, US 220 went through town as Business US 220 does today (though probably with signs to confirm this). PA 453 used to follow US 220 south to this intersection, one block south of the current Business US 220/PA 453 split. This view is along Business US 220 (former US 220) northbound, which turns left. Old PA 453 split and headed straight ahead here after entering from the left. Business US 220 was designated in Tyrone in 1998, but never signed. PA 453 stood alone in Tyrone from the 1970s until then.
Just ahead is an old PA 453 shield from the pre-bypass routing. This road is now SR 1012. Business US 220 is SR 4027 where not concurrently signed with PA 453PA 453 retains its SR 0453 designation along the Business US 220/PA 453 duplex.
