Source-derived summary

Pennsylvania Route 987 (PA 987) is a state highway in the Lehigh Valley region of the U.S. state of Pennsylvania. It runs 10.3 mi (16.6 km) from U.S. Route 22 (US 22) near the Lehigh Valley International Airport north of Allentown north to PA 946 in Klecknersville.

The route begins at a cloverleaf interchange with the US 22 freeway north of Allentown in Lehigh County and heads to the east of the airport as a four-lane divided highway called Airport Road as it crosses into Northampton County. PA 987 narrows to a two-lane undivided road and continues north, becoming concurrent with PA 329 as it heads into Bath. Here, PA 329 ends and PA 987 briefly runs concurrent with PA 248 before leaving the borough. PA 987 continues northwest and serves Chapman before ending at PA 946. PA 987 was first designated in the 1930s between US 22 (Union Boulevard) in Allentown and PA 946 in Klecknersville. After US 22 was relocated to its present freeway alignment in 1955, the southern terminus of PA 987 was cut back to its interchange with US 22, which used to carry Interstate 78 (I-78) as well.

In the early 2000s, PA 987 was widened into a divided highway and shifted to a new alignment near Lehigh Valley International Airport.
