US 422(E-W)/PA 28(N-S) Duplex

 

The western segment of US 422 and PA 28 join for 4 miles along a southern bypass of Kittanning in Armstrong County. The easternmost mile of the duplex is joined by PA 66.

David Greenberger 9/5/02

Northbound on PA 28, nearing the Kittanning bypass, which is the recently extended US 422 freeway on the south and east sides of Kittanning. PA 28 joins US 422 east to bypass Kittanning.

 

Timothy Reichard 3/9/03

The PA 28 freeway splits at the interchange. PA 28 north follows US 422 along the south and east sides of Kittanning.

 

Timothy Reichard 3/9/03

Approaching the same interchange along US 422 east. These signs appear to say that this eastbound roadway also carries both directions of PA 28. More likely, arrows were intended to be placed below the shields to indicate which route remain on the freeway and which exits.

 

Timothy Reichard 3/9/03

The western split trumpet interchange with PA 28.

 

US 422(E-W)/PA 28(N-S)/PA 66(N-S) Triplex

  

The US 422/PA 28 and PA 28/PA 66 duplexes overlap for one mile east of Kittanning in Armstrong County.

Timothy Reichard 3/9/03

The next interchange encountered on US 422 is for PA 66 south. This interchange is a partial interchange with ramps leading only to PA 66 south.

Timothy Reichard 3/9/03

A half mile ahead, a double trumpet interchange allows all the movements that the previous interchange disallowed. US 422/PA 28 exited here before the Kittanning bypass extension was completed. This interchange now marks the beginning of the US 422/PA 28/PA 66 duplex.

 

David Greenberger 9/5/02

The Kittanning bypass eastern extension was completed in late 2001 and bears three route numbers on the new roadway. US 422, PA 28, and PA 66 were rerouted onto the new bypass as shown above. The US 422 and PA 28/PA 66 split is just ahead and shown on the overhead green signs.

A closer view of the triplex shields.

 

Timothy Reichard 3/9/03

The US 422 east exit. This exit also leads to Business US 422 west, which was first signed when this bypass extension was completed in 2001. The PA 28/PA 66 duplex extends for 20 more miles—see below.

 

Timothy Reichard 3/9/03

Now heading southbound on PA 28/PA 66 to see the Kittaning triplex in the other direction. US 422 enters the freeway at this interchange.

 

Timothy Reichard 12/27/03

The westward view of the northern triplex split. Here US 422 exits from the old US 422 (now Business US 422, beginning here) to join PA 28/PA 66 southbound.

 

Timothy Reichard 3/9/03

Reassurance shields southwestbound. The hill underwent a bit of excavation to put the new freeway here.

 

Timothy Reichard 3/9/03

Before PA 66 exits at the partial interchange, the freeway is curiously signed as US 422/PA 28 only.

 

Timothy Reichard 3/9/03

PA 66 exits toward Ford City, which hugs the Allegheny River. The bridge ahead carries US 422/PA 28 over that river.

 

Timothy Reichard 3/9/03

On the other side of the river is the US 422/PA 28 western split. PA 28 follows a freeway for most of the way to Pittsburgh. Ahead, US 422 continues westward to meet the Business US 422/PA 268 duplex.

 

PA 28(N-S)/PA 66(N-S) Duplex

 

PA 28 and PA 66 join for a lengthy, 21 mile duplex from Kittanning in Armstrong County to New Bethlehem in Clarion County. The southernmost mile of the duplex is joined by the western segment of US 422.

David Greenberger 9/5/02

Northbound on PA 28/PA 66 at the northern end of the newly extended Kittanning bypass. The duplex was relocated onto the freeway upon its opening in December 2001. The freeway curves to the right to meet its old alignment and PA 85.

 

Timothy Reichard 3/9/03

The freeway ends at a traffic signal at PA 85 just around the next bend. After that, 20 miles of fast rural roadway over the rolling mountains to New Bethlehem.

 

Timothy Reichard 3/9/03

PA 28/PA 66 stick together all the way to South Bethlehem.

 

Timothy Reichard 3/9/03

PA 28 and PA 66 cross the Redbank Creek and split apart in New Bethlehem, each route leading to I-80. PA 66 serves Clarion to the north, while PA 28 heads to Brookville.
