MD 49 remains level until the descent of Haystack Mountain starts just before the intersection with Seton Drive, which leads to Bishop Walsh School and the site of Sacred Heart Hospital, which closed in 2009. The south leg of the intersection is an exit ramp from Exit 41 of westbound I-68. East of Seton Drive, MD 49 enters another residential area. At the bottom of the hill, the highway meets its eastern terminus at a five-way intersection, known as The Dingle, with north-south Fayette Street and Greene Street, the old alignment of US 220 that the highway meets at an oblique angle.
