U.S. Route 40 in Maryland partially coincident with U.S. Route 219 in Maryland
Garrett County
US 40 enters Maryland from Pennsylvania in Garrett County in the Western Maryland region of the state. From the state line, the route heads southeast on National Pike, a three-lane undivided road with one eastbound lane and two westbound lanes that soon narrows to a two-lane road as it descends Winding Ridge, which is part of the Allegheny Mountains. The road runs through wooded areas with some farmland and homes, with MD 733C looping to the north. US 40 continues southeast through sections of the Savage River State Forest and has a junction with MD 826H, at which point it curves east and passes businesses as a four-lane undivided road before intersecting the western terminus of US 40 Alt. in the community of Keysers Ridge. At this point, US 40 Alt. continues east along National Pike while US 40 turns south onto a two-lane road and comes to a cloverleaf interchange with I-68 and US 219.At this interchange, US 219 continues south along the two-lane road while US 40 heads southeast concurrent with I-68 and US 219 on National Freeway, a four-lane freeway that has a third lane for trucks while climbing hills and mountains. The road curves east and passes through another section of the Savage River State Forest, heading across Negro Mountain. Past the crossing of Negro Mountain, I-68/US 40/US 219 passes through a mix of farmland and woodland, coming to a diamond interchange with MD 495 to the south of the town of Grantsville. Following this interchange, the freeway descends a hill before it crosses the Casselman River. After crossing the river, the road ascends a hill, running through wooded areas and curving to the east-southeast. US 219 splits from I-68/US 40 by heading north on a freeway at a dumbbell interchange; this interchange also marks the southern terminus of US 219 Bus. From here, I-68/US 40 continues east-southeast along the National Freeway as it ascends forested Meadow Mountain. At the summit of the mountain, the road reaches an interchange with Lower New Germany Road (MD 948D). Past this interchange, the freeway descends the mountain. I-68/US 40 heads east through a mix of farmland and woodland, ascending and descending two hills and crossing the Eastern Continental Divide. Farther east, the freeway curves southeast and comes to an interchange with MD 546 in Finzel. Following this, the road heads across forested Savage Mountain.
