Pennsylvania Route 145

Pennsylvania Route 145 (PA 145) is a 20.89 mi (33.62 km) long north–south state highway in the Lehigh Valley area of eastern Pennsylvania. It connects Interstate 78 (I-78) and PA 309 in Lanark, Lehigh County to PA 248 in Weiders Crossing, Northampton County. PA 145 is the main north-south arterial into Allentown, the third-largest city in the state. The route enters the city on South 4th Street and follows multiple streets to downtown, where it follows the one-way pair of 6th Street northbound and 7th Street southbound. North of Allentown in Whitehall Township, a seven-mile (11.2 km) portion of PA 145 is known as MacArthur Road, named in honor of General Douglas MacArthur. MacArthur Road is a divided highway; between U.S. Route 22 (US 22) and Eberhart Road, it is six lanes wide with a Jersey barrier and jughandles while the remainder of the road a four-lane divided highway. MacArthur Road is the location of the main commercial center of the Lehigh Valley. North of Eagle Point, PA 145 becomes a two-lane undivided road that parallels the Lehigh River, crossing the river into Northampton County at Treichlers. The route continues along the east bank of the river and passes through Walnutport before reaching its northern terminus. PA 145 is dedicated as the Battle of the Bulge Veterans Memorial Highway in honor of the veterans who fought in the Battle of the Bulge.
