MD 180 parallels US 340 through a wide gap in Catoctin Mountain and continues northeast to the hamlet of Feagaville, where the highway intersects Mt. Zion Road at a roundabout and traverses Ballenger Creek. MD 180 crosses over I-70 (Eisenhower Memorial Highway) and intersects Butterfly Lane near Saint John's Catholic Prep before beginning a sweeping curve to the south. The state highway intersects Himes Avenues, which is unsigned MD 180B and leads to a ramp to westbound US 340 and US 15, at the same intersection as a ramp from that direction of the freeway. MD 180 crosses over US 340 and US 15 and receives a ramp from the eastbound direction of the freeway, then intersects Solarex Court and a ramp to the eastbound freeway that indirectly provides access to westbound I-70. Solarex Court provides access to a business park in the triangle formed by I-70, Jefferson National Pike, and the Frederick Freeway; this business park includes the historic home Linden Grove. MD 180 continues south as Ballenger Creek Pike, passing under I-70 before reaching its eastern terminus at Ballenger Center Parkway and a ramp to eastbound I-70 and I-270. Ballenger Creek Pike continues south through the suburb of Ballenger Creek.
