U.S. Route 219 Business is a business route located east of Grantsville, Maryland in Chestnut Ridge that runs 1.12 mi (1.80 km) from a dumbbell interchange with I-68/US 40 and US 219 north to an intersection with US 219, following Chestnut Ridge Road.

The route was designated after a freeway bypass was constructed around the borough to avoid the variety of turns that the highway previously made through the municipality.

The American Association of State Highway and Transportation Officials approved US 219 Alt.

The route's main portion is one lane, open only to northbound traffic, to avoid a steep descent into the borough.

[7] From its northern terminus in Salamanca to the hamlet of Bradford Junction, US 219 Business is concurrent to NY 417.
