MD 63 continues north as a two-lane undivided highway past several industrial parks and farms before intersecting US 40 (National Pike) in the village of Huyett, where the highway is paralleled by the old alignment, Huyett Lane, to the east. The state highway starts to curve to the northeast through farmland, crossing Rush Run and intersecting Broadfording Road before approaching the village of Cearfoss. MD 63 intersects MD 494 (Fairview Road) before meeting MD 58 (Cearfoss Pike) and the county-maintained portion of Cearfoss Pike at the Cearfoss Roundabout. Shortly thereafter, the state highway reaches its northern terminus at the Pennsylvania state line. The highway continues as PA 163, which immediately turns east onto Mason Dixon Road to closely parallel the state line east to I-81 and US 11. Williamsport Pike continues north as a quadrant route called State Route 3001 toward Greencastle.
