March 24, 2002 Photos by Timothy Reichard
Shiloh Road intersects both PA 150 and PA 26 near their junction and
just north of the Nittany Mall. The road from PA 150 to I-99/US 220 was
graded and widened. The Shiloh Road interchange will provide access between
I-99/US 220 and the commerical area near PA 26 and PA 150 to the east.
This offramp leads from I-99/US 220 southbound to Shiloh
This photo shows the same offramp, with the corresponding
onramp from Shiloh Road to I-99/US 220 southbound on the right side of
Now looking on the right side of the barrier, the clover
leaf onramp can be seen curving 180 degrees to the right to meet the mainline
freeway. This is the only clover leaf in the interchage. The other ramps
are diamond-style ramps.
Stone and drainage contours have been built into the middle
of the clover leaf.
This view shows the onramp and offramp meeting southbound
Here the clover leaf ramp meets the mainline. This view
is from the other side of the Shiloh Road overpass.
Here is another view of the offramp from southbound I-99/US 220.
Facing in the same direction (to the north), this is the onramp to I-99/US
220 northbound, complete with a view of the interstate to the north.
Here is a closer view of the mainline as it ascends the
distant hill. The PA 150 interchange is just to the north.
Here is the southbound view as seen from the Shiloh Road
overpass. The big green sign for the next exit can be seen in the distance,
as well as Innovation Park at Penn State in the farther distance.
Here is a zoomed-in view of the mainline to the south. It
descends past the big green sign for "Exit 74, Innovation Park, Penn
State University, Exit 1 Mile," curves to the right, crosses bridges
over Rock Road and Big Hollow Road, and curves back to the left to the
Park Avenue partial interchange. The buildings in the top left are Innovation
