Alternate US 220(N-S)/PA 150(N-S) Duplex

ALTERNATE
220
150

United States Alternate Route 220 and Pennsylvania Route 150 join for about 1 mile from just north of Milesburg to I-80 in Centre County.


Geoff Hatchard 4/27/03

Westbound on I-80/Alternate US 220 at Exit 158, where Alternate US 220 exits and joins PA 150. Previously, US 220 followed this routing. For historical photography, see the Old US 220/PA 150 page. The ALT tab shown here was added when the relocation took place and Alternate US 220 was born.

 


Geoff Hatchard 4/27/03

The offramp loops around to here, where the first reassurance shields are posted. The overpasses carry I-80/Alternate US 220.

 


Timothy Reichard 12/27/04

Just south of the I-80 overpasses, the interstate dumps Alternate US 220 traffic onto PA 150 here.

 


Timothy Reichard 12/27/04

More reassurance shields are posted. The 220 uses a wider font than usual, while 150 uses a narrower font than usual.

 


Timothy Reichard 12/27/04

The duplex meets PA 144 about a mile south of I-80. The three routes form three duplexes that meet at this partial-cloverleaf interchange. The Alternate US 220/PA 144 duplex begins ahead, while the overpass carries PA 144/PA 150 toward Milesburg.

 


Timothy Reichard 12/27/04

Northbound on PA 144/PA 150 at the same interchange. Rather than replacing the sign from the US 220 days, ALTERNATE banners were attached.

 


Timothy Reichard 12/27/04

A right turn splits PA 150 from PA 144 and begins the Alternate US 220/PA 150 duplex.

Northbound reassurance shields precede a new sign goof.

Now northbound on Alternate US 220/PA 150 and nearing the I-80 interchange. Another ALT tab was added here to note the change from US 220 to Alternate US 220 (left photo). Then the sign was replaced with a sign goof. I-80 travels east with Alternate US 220 north, not west. Another oddity is that this new sign appeared well after US 220 was changed to Alternate US 220, but ALT was added above the sign again instead of included in the main sign.

 


Geoff Hatchard 4/27/03

The northern split. Alternate US 220 turns left onto an onramp to I-80 and loops back across the road from left to right ahead. PA 150 continues ahead on the pre-I-80 alignment of US 220 (Old PA 64).
