[edit] Route description

PA 28 at exit 12A (Pittsburgh Mills Blvd.).

[edit] Pittsburgh area

Heading north from the I-279/I-579 interchange, PA 28 is a surface street, running along the north bank of the Allegheny River. At the 40th Street Bridge, PA 28 becomes a limited-access highway, a property the road maintains throughout its run in the Pittsburgh metro area. In Etna, PA 28 interchanges with Pennsylvania Route 8 at exit 5 before departing the Blue Belt, which PA 28 is part of from I-279/I-579 to this point, at exit 6 near Aspinwall. Outside of Cheswick, PA 28 meets Interstate 76 (the Pennsylvania Turnpike) and Pennsylvania Route 910 at exit 11.

[edit] Cheswick to Kittanning

PA 28 southbound from exit 14 (PA 366).

From the Pennsylvania Turnpike to U.S. Route 422 west of Kittanning, PA 28 has eight interchanges, including exits with Pittsburgh Mills Boulevard (exit 12A), Pennsylvania Route 366 (14), and Pennsylvania Route 356 (17), while continuing to parallel the Allegheny to the east. At exit 19, PA 28 merges with the limited-access US 422 and heads east along US 422 as it proceeds south of West Kittanning.

Upon crossing the Allegheny River and entering Kittanning, US 422 and PA 28 interchange with Pennsylvania Route 66. PA 66 then joins the concurrency for two miles to an exit with U.S. Route 422 Business southeast of downtown Kittanning. Here, US 422 leaves the freeway and heads east toward Indiana while PA 28 and PA 66 remain concurrent as they progress northward.

[edit] Kittanning to New Bethlehem

The 39 mile long freeway ends with a concurrency with Pennsylvania Route 66. In Rayburn Township, PA 28/PA 66 intersects the western terminus of Pennsylvania Route 85. After PA 85, PA 28/PA 66 head towards the northeast. In South Bethlehem, PA 28/PA 66 become North Street and Broad Street then intersecting the northern terminus of Pennsylvania Route 839.

[edit] Clarion County

After crossing the Redbank Creek, PA 28/PA 66 enters Clarion County and New Bethlehem. In downtown New Bethlehem, PA 66 splits off from PA 28 and making the PA 28/PA 66 duplex one of the longest concurrencies in Pennsylvania. After the split, PA 28 heads northeast as Broad Street paralleling the Redbank Creek. In Hawthorn, PA 28 is called Brookville Street and meets the western terminus of Pennsylvania Route 536. North of PA 536, PA 28 begins to slide to the north instead of the northeast.

[edit] Jefferson County

In Summerville, PA 28's course begins to slide towards the northeast again and in Summerville, PA 28 is called Harrison Street. In Clover and Rose Townships, PA 28 parallels many railroads tracks that even cross it. In Brookville, PA 28 has a Wrong-way concurrency with U.S. Route 322 and Pennsylvania Route 36. The reason of the Wrong-way concurrency is that PA 28 is heading north while PA 36 is heading south on the concurrency with US 322. In downtown Brookville, PA 36 splits off from US 322/PA 28. Then after crossing the North Folk Creek, US 322/PA 28 meet the southern terminus of Pennsylvania Route 968. East of PA 968, US 322 splits off from PA 28 at a "T" interchange. East of Brookville in Pine Creek Township, PA 28 intersects Interstate 80 at exit 81 a Diamond interchange. North of I-80, PA 28 continues north as a local road without intersecting another route for more than 14 miles. PA 28 passes through the many wildlife in Pennsylvania through a forest region. In Brockway, PA 28 is called Main Street before terminating (ending) at a "T" intersection with U.S. Route 219.
