State Route 1002 (SR 1002), locally known as Tilghman Street and Union Boulevard, is a major 13.8 mi (22.2 km) long east–west road in the Lehigh Valley region of eastern Pennsylvania. The majority of the roadway is the former alignment of U.S. Route 22, maintained by the Pennsylvania Department of Transportation as a Quadrant Route, and is not signed except on small white segment markers.
Tilghman Street begins at Pennsylvania Route 100 in Fogelsville, though SR 1002 continues west on Main Street, also known as the old US 22, to the intersection of Church Street (SR 3014). It becomes Union Boulevard just east of the bridge over the Lehigh River in Allentown; SR 1002 ends at the interchange with Pennsylvania Route 378 in Bethlehem. Union Boulevard continues over Monocacy Creek, which forms the border between Lehigh and Northampton Counties, and ends in downtown Bethlehem.
As of 2007, an average of 21,018 vehicles used the highway daily in South Whitehall Township and 21,706 in Allentown.
