· Catoctin Mountain Hwy.
37.85 mi. in Maryland; from VA line at Point of Rocks north to PA line north of Emmitsburg.
Marked north-south. NHS: Entire length in Maryland. Associated Secret-Obscure Routes: The north-south backbone of Frederick County, US 15 once followed what is now MD 85 south to MD 28, then west to Point of Rocks before its current duplex with US 340. The Frederick Bypass was built in the fifties as a pre-Interstate expressway. The US 15 section is not Interstate standard. So where are Exits 1-4? Buried under I-70's current numbers; exit 1 was Patrick St. swinging westward along US 40's piece, then north on US 15 from exits 5-9. North of Frederick, 15 is a wide 4 lane divided highway along the eastern slope of Catoctin Mountain. There is a Business US 15 through Emmitsburg. US 15 becomes a limited-access highway again upon crossing into Pennsylvania north to Gettysburg. |
